Cisco 1841 router 12.4(3i)
I have 2 disconnected public IP spaces - both from the same ISP. I am trying to NAT an IP from the second IP space to a sub-interface on the inside.
I have a primary and seconday IP on the outside interface and several sub-interfaces on the inside - each on a different vlan with isolated servers/services on each vlan.
I can't get a NAT to pass anything *except* ICMP on the IP in the second block.
That is to say, my access-list is tripped with a ping 126.96.36.199 and the ping replies. I see the icmp on the inside host (wireshark), so I know it's not just the router replying. however, the access-list for 188.8.131.52 is *not* hit when I try *any* other port - http, https, ssh, rdp..etc.
I am not mixing IP's from the public blocks into the same vlan on the inside (i.e., IP's from block 1 are NAT'd to VLAN 100, 101, 102, and I need IP's from block 2 NAT'd to vlan 103).
