Cisco VLANS not quite seeing each other
Posted on 2011-04-25
I have 2 VLANS on a Cisco 881 and a Sonicwall TZ210.
Vlan A is 10.0.7.0
VLAN B is 10.0.8.0
VLAN A: 10.0.7.10
VLAN B: 10.0.8.11
VLAN A: 10.0.7.249
VLAN B: 10.0.8.249
In between is 2950 Switches. Both routers are configured as Trunks on the Switch.
Both subnets can ping each other usign all four IPs as gateways.
However, on both VLANS, we have a few webservers. When connected to VLAN A as gateway (either the Sonicwall or Cisco) we can see everything we need to only on VLAN A but nothing on VLAN B. I can ping VLAN B without any issue.
When I try VNC, RDP, or HTTP from VLAN A to B, I get timeout. It works the same from VLAN B to VLAN A.
I think I may have an ACL issue, but I am not sure.
Thoughts on this?
