I have 2 cisco 6513 switches with full redundency and its connected to access swictches. We have 6 vlans, our all servers are connected to VLAN1 including the ISA server with IP 10.0.1.108. When ever I connect the pcs to the VLAN 1 they work fine and they can access internet using ISA server. If i assign the same PC to vlan 2 it gets its ip from DHCP server & can access all other network resources but it cannot have an access to the internet. I am using the same proxy ISA 10.0.1.108 port 8080. Do you have any idea why its not working. Please update me ASAP.
