Hello,
I'm new to the Juniper forums so please forgive me if I have posted in the incorrect place or anything!
I’m experiencing issues with a PPPoE connection from an vSRX running as a gateway.
It’s more a learning experience than a real issue. I seem to have get all the basics working.
The issue I’m having is the PPPoE connection will drop randomly during the day/ night seemingly regardless of load.
My PPP config:
set interfaces pp0 unit 0 apply-macro ISP-Connection
set interfaces pp0 unit 0 ppp-options chap default-chap-secret "insert password here"
set interfaces pp0 unit 0 ppp-options chap local-name "insert username here"
set interfaces pp0 unit 0 ppp-options chap no-rfc2486
set interfaces pp0 unit 0 ppp-options chap passive
set interfaces pp0 unit 0 pppoe-options underlying-interface ge-0/0/0.0
set interfaces pp0 unit 0 pppoe-options auto-reconnect 2
set interfaces pp0 unit 0 family inet mtu 1420
set interfaces pp0 unit 0 family inet negotiate-address
I've set traceoptions on pppoe and am getting the following logs when the connection drops and then restarts:

So really, I’m a bit stumped about what this is actually telling me but it’s pretty much the same every time it disconnects.
I can see that I am sending PADT's, does this mean that I am terminating the connection? or is this in response to the connection being terminated?
Is my config right? did I miss something?
I will say that this disconnect issue was also an issue I had on a different firewall on the same connection, as well as the provided router that the isp gave me. So, I’m only partly sure it’s not my fault, but if someone can break that down and explain what its telling me then I will be able to "hopefully" go about fixing the issue.
Any help would be amazing!
