Issue with 2 ip block, one not routing back PIX 515e
I am having somewhat of an issue here. We currently have a PIX firewall placed in the datacenter managed by us that we just received a second block of ip address. (different subnet then the first). The first block routes fine, back and forth with no issues. The second block comes to the PIX firewall and is routed to an internal ip address just fine. The pix allows this but when it is getting routed back from the internal ip address and is translated and pushed to the internet from the pix it is getting dropped simply. I am able to ping the second block default gateway to the ISP just fine. I have a default route setup to be sent to the first ip address block. What is the best way to set it up to where both blocks can be routed back and forth through the firewall? Both blocks do hit the firewall and go through the firewall according to the logs.
You will be able to have the reply traffic that comes in through one ISP go out via that same ISP. Let''s say that 192.168.1.12 is an IP in your 2nd ISP block and its public IP after translation should be 126.96.36.199. Please try adding the static NAT as follows for www traffic:
