Two Residential circuits SRX failover solution? Possible?

December 25, 2017, 2:06 pm

I currently have 2 different ISPs residental circuts and one SRX 240 when I work from home.

My goal is to utilize the 2 different carrier circuits for continuous connectivity and/or separate traffic, if possible.

Since they are residential circuits the SRX receives a DHCP address which it can hold forever as long as device is on, which it is (with UPS).

 

1. Can I have a failover solution for two ISPs on the same SRX device? (let's say ISP A on ge0/0 and ISP B on ge0/1)

 

2. Furhtermore, can i route heavy traffic like streaming, music, games, etc through one circuit and light traffic like VOIP, email, web throught the other? (Lets say Zone: Phone, Web, DMZ, LAN, Email)

 

Any suggestions are greatly appreciated.

Thanks.

Hi Clubber, 

 

It is possible to have two ISPs terminating on 2 individual interfaces on the SRX by configuring Filter Based Forwarding and have them to route different type of traffic. They can also act as primary and backup ISPs and hence providing redundancy. 

 

Please refer to this KB artcile which explains this with example. -> https://kb.juniper.net/InfoCenter/index?page=content&id=KB17223 

 

Let me know if you have any queries

Hi serdar, 

 

The messages you see are related to the dataplane CPU utilization. This is always related to the traffic pattern hitting the device at that point. It could be that the rate of traffic hitting the SRX is reaching its device limitation in terms of packets per second (pps) and bytes per second (bps) .

 

Do you know when you being the speed test , what are the pps and bps values of traffic hitting the SRX? 

 

When you run the speed test, capture the below data at least 3-5 times from the CLI of SRX and attach the outputs here, 

 

set cli timestamp

show security monitoring performance spu

show security monitoring performance session 

show interfaces extensive | no-more 

 

In Realtime you can run the command "monitor interface traffic" to see the pps / bps hitting each interface .

Hi badgerdata,

 

I understand your current set up and requirement is , 

default route to internet is via ge-0/0/0 part of Internet security zone 

LAN facing interface is ge-0/0/1 part of Internal security zone

 

During failure of primary route, the default route points to 192.18.0.2 which is reachable via ge-0/0/1.

 

In that case you would need a security policy from-zone Internal to-zone Internal and allow the corresponding subnets and application to pass through as traffic from LAN ingresses the SRX on ge-0/0/1, does a route lookup and needs to egress again back via ge-0/0/1.

 

Try adding a security policy as mentioned above to see if it works fine.

Re: Using vlan interface for source nat?

I could only get it to source NAT when using family inet / physical interface in my nat1 zone instead of l3-interface / vlan. When I tried putting it together like the above, I couldn't get it to work, but I will reload the config and see if vlan.30 is up/up. Thank you!

Hi Folks,

 

My 2 cents on this…

 

We need to identify the top talkers and suggest customer to put in a firewall filter to discard this traffic to see if that helps to improve CPU/PPS

It would be nice to have a physical diagram attached to the article KB17223  so one can see how things are connected.

In addition, one must remember that these are DHCP interfaces. If one interfaice fails, in order to reset the connection one must break the lease with ISP.

 

Does the solution requires the use of another device like switch? What's happening here:

fe-0/0/2 {
        unit 0 {
            description ISP1;
            family inet {
                address 10.1.1.1/24;
            }
        }
    }
    fe-0/0/3 {
        unit 0 {
            description ISP2;
            family inet {
                address 10.2.2.1/24;   

 

I am not sure I understand the redundancy aspect in this article since some traffic is routed on one ISP and the rest on the other. If one ISP goes doesn what happens to its traffic?

with regards to 'In addition, one must remember that these are DHCP interfaces. If one interfaice fails, in order to reset the connection one must break the lease with ISP.', this can be accomplished using RPM and FBF as in KB22052.

Re: I am not able to access my protected resources via Dyn VPN from public remote site.

Proxy ARP is required only when your remote protected resources and address assignment pool are on same subnet. As per the initial configuration you have shared, below given are the protected resources and the pool which are in diffrent subnets. In this scenario we dont need proxy ARP.

 

remote-protected-resources 10.2.72.0/28;

 address-pool 10.10.10.0/24;

 

One of the latest update from you shows remote protected resources as '10.0.0.0/8', did you made this change as part of troubleshooting or this is the correct value?

If so can you share the address pool cooresponding to this?

 

If thats also in 10/8 subnet we need proxy arp, and we can do proxy arp for whole subnet (pool) or use a different subnet for address assignment.

Hi Clubber, 

 

Thanks for your reply. We will integrate a diagram to the kb article to make things clear . I have attached a representational image here. 

 

"Does the solution requires the use of another device like switch? What's happening here: "

 

Fe-0/0/2 is connected to ISP1's router , a l3 device and fe-0/0/3 is connected to ISP1's router which is another physical device. There is no switch required in the upstream direction unless the SRX is a HA cluster . 

 

"I am not sure I understand the redundancy aspect in this article since some traffic is routed on one ISP and the rest on the other. If one ISP goes doesn what happens to its traffic?"

 

The redundancy aspect is also covered in this configuration by the rib groups . Rib groups help to share routes between the routing instances. 

 

In this example in the routing-instance routing-table-ISP1 , default route will be pointing out to next-hop 10.1.1.2 (ISP1's gateway IP)which is most preferred route and then next preferred route is via 10.2.2.2 (ISP2's gateway IP). So when the interface fe-0/0/2 goes down, the default route will point to  10.2.2.2 . And similarly in the routing-table-ISP2 also the routing preference is configured for the ISP1 route to take over when fe-0/0/3 goes down.

Thank you. The diagram helps a lot.

Just to clarify, how does failover works if one circuit goes down since that same circuit only handles part of the traffic i.e. 8080 etc.

 

Please explain Rib groups and their purpose.

Need help understanding setup of EWF on SRX

Hello,

 

I am new here and new to the sophisticated router our SRX320.

This may not be the correct forum to ask this but, I have limited knowledge of installing and configuring

the UTM package that I purchased. Also, that it was brought to my attention the support is only break and fix, therefore

Juniper does not help with setting up the device. I was told that Dell would assist you through the setup process but I

was told that the Juniper was a better product and had better support.

Any help would be greatky appreciated,

Thank You

CharlieC

Welcome to the SRX with UTM features.  Sorry you seem to be getting the run around from your vendor and support.  I have moved this to the correct forum category.

 

This general overview may help with understanding all the features in your license for UTM.

 

https://www.juniper.net/assets/uk/en/local/pdf/books/day-one-poster-utm.pdf

 

For the enhanced web filtering, these would be the basic setup instructions.

 

https://www.juniper.net/documentation/en_US/junos/topics/example/security-utm-enhanced-web-filtering-configuring.html

 

But you also need to be aware that many web sites these days use ssl instead of plan http.  This means the url is encrypted and cannot be read without decryption.  So you likely will also want to setup a ssl forward proxy on the SRX in order to control access to ssl sites.

Hello everyone,

 

How can I limit download and upload speed on Juniper SRX100? I am trying to limit the download speed for all connected devices to about 20-25 Mbps and limit the upload speed to about 3-4 Mbps. I read that some people do it with firewall and whatnot but I am not sure how I can do it myself. Please help thank you!
