Is there a way to have one physical interface host more than one hw-address? I am connecting an SRX210 to a service provider device that is very specific on what is allowed. I am having it installed in 3 days and would like to have the SRX ready to go at install.
From what I have read the static IPs that I will be assigned will exist on the service provider gw and that device's LAN interface will host one of the addresses in my /29. I understand that I must aquire each of the public IPs from DHCP only and can't statically assign them. I can't confirm this, but I understand that the arp may be locked in at that point untill a gw reboot, at which time the statics would be re-aquired by the same method. I pray this isn't all the way things will actually be.
If I can bind 4 additional mac-addresses to the physical interfaces and associate them with the proxy-arp ips, I might can get this working (until the gw loses power).
I'd want a single srx interface ge-0/0/0 unit 0 to basically use:
1.1.1.1/29 (actual int ip via dhcp) 11:11:11:11:11:11 (whatever the real physical mac address is)
1.1.1.2/29 (proxy-arp) 11:11:11:11:11:12 (no idea if this is even possible)
1.1.1.3/29 (proxy-arp) 11:11:11:11:11:13 (seems unlikely)
1.1.1.4/29 (proxy-arp) 11:11:11:11:11:14 (I'm almost sure this is impossible)
1.1.1.5/29 (proxy-arp) 11:11:11:11:11:15 (I'm nearly giving up, but I've already typed this much...)
The SP GW would have 1.1.1.6/29 as it's LAN IP and would be my def-gw.
I may find that it's not as restrictive as this, but I have read conflicting reports and I am trying to prepare for the worst and learn somehting in the process. BTW, it's AT&T Uverse Gigapower with a /29 static ip assignment and the new PACE gw that will not do any kind of bridge mode. People say it's very strict.
Thanks for your time.
