I have a site-site VPN tunnel setup with two Cisco ASA 5505. Site1 hosts a Windows DHCP server, Site 2 is sending out DHCP requests but not getting IPs from the DHCP server.
fix this for me please quick.
Hello, i am a CCNP certified and i know that the ASA does not forward DHCP packets across interfaces. You either need to make the ASA DHCP server or make a new DHCP server on the local subnet
The ASA has a DHCP relay feature that enables you utilise a DHCP server on a different network.
However this feature only works accrsss interfaces e.g DMZ to INSIDE etc.
It will not work across a VPN tunnel as far as I know.
It would not be a good design to get DHCP across the VPN because if the tunnel is ever down the local clients won't be able to get an IP Address, browse the internet etc.
The ASA can provide full DHCP functionality for the local clients.
Be wary of anyone who says they can do this for you as im pretty sure the ASA cannot do DHCP relay across VPN tunnels.
If you would like assistance with a design that will work for you please let me know.
Cheers
