After getting the service installed, it turns out that dhcp is not required to pull the IP. The customer gw does only allow one IP to forward to one MAC. When I tried with proxy-arp and pinged for a remote device, only one ip would work at a time. The Customer gw has a crappy gui and although I couldn'e see much, I could see that the the same mac was associated with x.x.x.1 and upon refresh might then be associated with x.x.x.2.
Your vrrp suggestion was brilliant. I tried that and now it sees .1 on the physical, .2 and .3 on their perspective virtual vrrp mac addresses. Thank you. I am not sure I would thought of that.
The service is AT&T uverse. I am getting fiber to the home with 1Gbps (SRX only allows a max of 220Mbps(ish)) for about $80/mo, so it's worth the trouble.
Again... thank you.
