ip helper-address not available on C870 router

I discovered the interface config command ip help-address is not available on my C870 router running

Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(4)T4

How can I get my DHCP client PC requests coming in on Fa0 to be routed via my IPsec site-to-site VPN back to my home office network DHCP server?

Thanks.

I believe that the issue is that interface fa0 on the 870 router is a switch port not a routed port. I believe that if you configure the ip helper-address on the VLAN interface that it should work (assuming that you have things like routing to send the request through the VPN).

Thanks Rick.

I'll try it on the VLAN interface.
