We currently have a main site with 3 branch offices.
Our main site has the DHCP server. We use ip helper to forward DHCP requests across our T1 WAN links to and from the branches.
We want to build redundancy into our WAN links. Our best option so far is to setup DSL internet connections at each branch and run VPN tunnels in the event that our main site goes down.
Do the 851/871 series support ip helper? I’m not new to cisco equipment but I rarely work on it. I’m not sure if the 851/871’s can run ip helper through a VPN tunnel. So far I havne’t found any information that would directly answer my question.
