Subnet using Switch-based Routing Cannot Access Internet
Posted on 2007-10-19
In the following configuration, can anyone tell me why clients on subnet 192.168.20.0 are NOT able to access the internet? The two other subnets are hitting the internet just fine. I can't tell if the problem is on the firewall or the switch configuration, but internet access for this subnet is the ONLY communication problem I can detect.
Router (Cisco 2600 series)
Firewall (PIX 515E), 192.168.0.3
Switch (Cisco 3750e), 192.168.0.1 ..... gateway set to 192.168.0.3 ..... 1 VLAN (default) ..... routing enabled ..... static routes established for destination 0.0.0.0/0 to gateway 192.168.0.3 and destination 192.168.20.0/24 to gateway 192.168.0.4 ..... subnet 192.168.10.0/24 assigned to port 3
Switch (Cisco 3750s), 192.168.0.4 ..... gateway set to 192.168.0.1 ..... 1 VLAN (default) ..... routing enabled ..... static route established for destination 0.0.0.0/0 to gateway 192.168.0.1 ..... subnet 192.168.20.0/24 assigned to port 2 (192.168.20.1)
Clients on subnet 192.168.20.0/24 using gateway 192.168.20.1
NOTE: Subnet 192.168.0.0/24 clients connected to the secondary switch are also able to access the internet. The ONLY clients having a problem are on subnet 192.168.20.0/24.
Thanks for any ideas!!!
