ip helper-address for vpn?

In my home network I have quite a few subnets, as I'm sure most of you do too.

Every once and a while I have some friends come over and plug their laptops into the network to play some older multiplayer games. As they are in a different subnet than my computer I use the "ip helper-address" command to send the broadcasts around and it works rather well.

Now I have an Easy VPN Server on a router and I want to achieve the same thing: directing cretin broadcasts from the vpn clients to other networks. This is where I'm at a loss. From what I've gathered there is no "interface" in which you can control traffic to do something like ip address-helper.

I'm hoping you guys had some ideas.

Thanks in advance,
Eco

If the specific part of the documentation you're talking about is "Configuring an Easy VPN Server to Obtain an IP Address from a DHCP Server " then I don't think that will work for my situation as I need to define specific udp ports.

Though, further down in the text was something interesting: "...when the server uses IPsec virtual interfaces." I'm thinking this is the road I need to go down. I may be able to use ip helper-address on a virtual interface.

The easy VPN server acts as a DHCP proxy using the link I provided, it will send a request to the DHCP servers you specify using the "dhcp giaddr" command to determine what scope it should be allocated from.

I'm a bit confused. The dhcp currently setup is fine. I have no need to forward dhcp broadcasts.

I'm trying to forward specific broadcasts from older applications. For example udp port 1117.
