Cisco to SonicWall ARP

timbrigham asked
I have a couple sites that are set up with Cisco routers that handle the DHCP and other network services locally on the router. The problem that I'm running into is that I have a handful of users that need specialized firewall rules applied to them. Since I'm using DHCP, I need to log into the firewall and update their settings whenever their IP address changes, which is frequently because most of these guys use laptops.

I'd love to be able to use MAC based security lists as described in in the SonicWall administrator's guide, but in order to do that, I need to have a complete copy of the ARP cache from the Cisco router copied to the SonicWall. I'm thinking it'd just be a push from the Cisco, but I don't know enough about the setup to be sure.

Can this be accomplished?

If the problem is their IP changing, couldn't you just setup DHCP reservations for them?


I hadn't thought about that;I technically could. If I don't hear back on a way to forward the ARP table that is just what I'll do. I'd need to create nearly 50 reservations though; each person would need a reservation added on 7 or 8 subnets, and I have at least half a dozen people that need the entries added.
I'd really like to be able to make use of the MAC lists in the SonicWall devices.


I set up static IPs for certain offices, but that still didn't help with the roaming access I was hoping to set up. It's a good compromise though. Thanks for your help.
