I do have a small question for you..
I have 3750 configured with around 30 vlans. The default vlan1 has an ip 192.168.1.1 and one of the ports in that vlan is connected to a PIX. Half of those vlans have access to the PIX as they suppose to. Now I have a different network configured in other vlans with address 18.104.22.168 breaked down in different subnets. Its subnet is a vlan. Now I want all these 11.110.28.x vlans to go to a router (1761) and not to the pix at all. So basically VLANS 1 - 222 go to the PIX (vlan1) and VLANS 600 - 800 go to the router vlan601. If we forget vlans 1 - 222, I have 6 GigabitEthernet, 4 of those go to a vlan600 which are the servers one is going to a 2950 gigabit port and they are trunk auto 802.1q which is seperated in vlan621 vlan 622 and so on, and the other port of 3750 is going to a router (1761) in vlan 601 with the ip address 22.214.171.124 255.255.255.252. The router has a WIC-4esw and can display the vlans from 3750, I assigned both the 3750 port and the 1761 port to be switchport mode access in vlan 601. I changed the interface for vlan 601 ip address to 126.96.36.199 255.255.255.252..
Uffffff..... Now I can ping from 3750 the 188.8.131.52 which is the router and also from router the ip 184.108.40.206 which is the 3750. My problem is that I can not ping the router from any other vlan.... WHYYYYYYYYYY?
