I have an ASA 5520 connected via port G0/3 to a 3825 router that hase a fast ethernet switch module installed in it. I built a vlan interface and assigned port 2/0 to that vlan.
I cannot pass any data thru the firewall from the router nor can I ping the router from the firewall. I have hard coded the port on the ASA to 100 full and also on the router.
When I connect a PC directly to the ASA I can get out with no problem. Here is a snapshot of both configurations.
From the router
description ACSB wireless guest VLAN
switchport access vlan 168
ip address 192.168.168.2 255.255.255.0
From the ASA
ip address 192.168.168.1 255.255.255.0
Any suggestions? Also, the router is not showing up in the arp table on the ASA but the ASA shows up in the arp table of the router. Both interfaces are showing up up with no errors.
