Our main office is connected to a very small branch office via a T-1 line. Connected to the T-1 is a C2821 at each site.
There is an ASA5520 at the main office, and an ASA5510 at the branch office. Traffic between the sites uses a Site-to Site VPN tunnel.
We have DHCP servers at the main office, but none at the branch office.
I set up a dhcp service on the branch office ASA for those few clients, but have had issues with that scenario, and am looking for an alternative.
My question is this:
Using dhcprelays and ip-helpers, is it possible for the branch office clients to use the main office's DHCP servers?
Can a DHCP request and reply go through two ASAs (Site-to-Site VPN tunnel) and its associated routers?
