I'm trying to get a PTP T1 configured for the first time and am struggling a bit with the routing. I don't have access to the current configs right now but here's the gist of it:
Setup: PIX515E (8.x) <--> Cisco 2611 <--> PTP T1 <--> Cisco 2600 <--> PIX501 (6.x)
Site A: PIX515E: inside IP 10.0.0.1 Cisco 2611: ser0 IP 192.168.1.1, eth0 IP 10.0.0.2, route 0 0 192.168.1.2 PCs: route add 10.0.1.0 10.0.0.2
Site B: PIX501: inside IP 10.0.1.0 Cisco 2610: ser0 IP 192.168.1.2, eth0 IP 10.0.1.2, route 0 0 192.168.1.1 PCs: route add 10.0.0.0 10.0.1.0
Both routers can ping each other's serial interface but not the ethernet interface. At Site A I enabled hairpinning on the PIX515E but I don't think I have the config complete because I still had to add route on PCs before being able to ping Site B devices. At Site B I can't ping anything at Site A unless it receives a ping from Site A first and I had to add routes to the PCs because the 501 doesn't support hairpinning.
Trying to learn this from the Internet in a pinch has got me all confused, so I'm wondering:
1) what the right routes to set on each router are given this config and do I need any other options? 2) should I use hairpinning on the 515E (if so, what commands do I need to look at to complete it) or should I just add routes to each PC?
