DHCP helper on Cisco ASA

Hello, I have site to site vpn tunnel and one side is a cisco ass.


I am trying to use it as a hdcp helper, but its not working as expected. The site to site tunnel is working fine. I just cannot get dhcp to work. Any thoughts on what I should look for? The dhcp server is on the other side of the tunnel.

fw# sho run | i dhcp
dhcprelay server outside
dhcprelay server outside
dhcprelay enable inside
dhcprelay setroute inside
dhcprelay timeout 60

DHCP relay over a site-site VPN is a bit tricky.

Please refer to this article on some tips on setting it up.
