i got 10 VLANs on a catalyst 4503, which works perfectly. There is a default route (0.0.0.0 0.0.0.0 172.16.254.1) which routes everything to the internet, 172.16.254.1 is an ASA 5510. Recently i added a VLAN for test purposes, VLAN 100, with ip address 192.168.254.111, and i assigned it to gige port 5.
I also have a broadband "dlink router" which has ip address 192.168.254.2. The setup is as follows.
on catalyst 4505, on port 5 an ethernet cable cascades to an hp 2626 switch (unmanaged mode), onto the hp 2626 i plugged in my broadband router.
For every desktop on VLAN 100, i am using the following:
ip addr: 192.168.254.115
using the above configuration on each desktop, i can ping other vlans (all gateeways and nodes), browse files etccc, but no internet access.. It seems to route through the default route.
If ever i change the default gateway on any desktop, put it to 192.168.254.2, i can have internet access, i can ping only other vlans, for eg:
i can ping 172.16.1.1 which is the ip of vlan 11, i cannot ping 172.16.1.2 which is a desktop..
Is there a way to add another route for VLAN 100 to go through 192.168.254.2 for internet? And at the same time use default gateway 192.168.254.111 on desktops so as to be able to browse files on other nodes on other vlans.. I dont want to go through the ASA
Attached my conf file..
