My network consists of two VLANs. Hosts in one VLAN have historically had no access to hosts in the other and vice versa. There are internal servers on both VLANs and each has a firewall/router supplying internet access, each with a separate DHCP and DNS, etc. There is now a need for hosts in VLAN2 to access some servers in VLAN1.
Switch is a 3226 (3CR17500-91) running 1.2.0.1.
VLAN1 is 10.3.148.0/24. VLAN2 is 10.3.149.0/24. I am trying to get requests to the 10.3.148.0/24 subnet from VLAN2 to be routed correctly using inter-VLAN routing. The switch has interfaces (10.3.148.2 and 10.3.149.2) on both subnets. Have tried many routing entries, consulted the implementation guide and 3Com's knowledge base, searched the web, etc. Cannot get traffic to pass between the VLANs. Changed default gateway on hosts to 10.3.149.2. The switch default gateway and default route is 10.3.148.1 (the router on VLAN1). The other router is at 10.3.149.1. Traceroute shows connectivity with the hosts on VLAN2 and the target servers on VLAN1. First thing (and what seems to my simple mind as though it has the best chance of working) I tried was a route of 10.3.148.0 255.255.255.0 10.3.148.1, but host 10.3.149.4 can't ping 10.3.148.105.
Is there a guide to layer 3 routing with examples? Everything I read suggests this is possible, but doesn't give examples of what the routing entries would be.
