ISP network topology
Hello network experts,
I am new on this forum and i would like to ask if somebody have experience with ISP network architecture. I want to simulate real network situation as you can see in screenshot but I have some problems with routing or NAT configuration.
Now the network shown in screenchot works fine and I can do ping from workstation 192.168.8.166 to external network 188.8.131.52. Also i can ping from 192.168.1.1 to 184.108.40.206, so basically network works fine but there is one problem with NAT or routing (probably).
I have assigned some specific external IP (NAT) for inside host 192.168.8.165. This IP is from another range than between PIX(FW0) and ISP router(R0). So ISP assigned me 220.127.116.11/27 network range for my servers to be reachable (NATed) outside internet (in this case R0).
On PIX(FW0) I created new static for example nat 192.168.8.165 --> 18.104.22.168 and now I want to make this IP available from another network (like from internet) for example from network 22.214.171.124. But when I try to ping from 126.96.36.199 result is timeout.
How should I configure R0 to be able to route NAT pool (188.8.131.52/27) to another networks ??? This IP addresses are real and it is range what I got from ISP provider and I would like to know how it is configured on ISP side.Could someone help with it or tell me how does it works ?
My network is terminated by PIX and there is no other router on my side. I am connected to ISP side with normal ethernet cable (no serial cable or other type of connection, no frame relay) Which routing protocol should I use ?
I hope that description is clear.Thank you very much for help :-)
