folks
i have a 2821 ISR with a HWIC-4ESW installed and a firewall running ospf on the end of one of the switch ports
the switchport is assigned to a vlan and the vlan interface has an ip
my problem
the switchport is layer 2 and won't see the firewall, i can't even see a mac-address! the line is up as is the protocol so figure its a config problem
i've tried setting the firewall interface in the same vlan number - no joy
i need ospf to run between the firewall and the router - has anyone any idea of what i can do
i think there's a compatibility problem with the HWIC-4ESW and may need another L3 card - can i get one for the 2821?
thanks to anyone taking the time to reply
