Hi,

We have a 2820 used for VPN connections into the office. We are trying to use an internal DHCP server to lease PPP addresses, however, the relay setting is being ignored.

Under LAN/General Setup we have populated "DHCP Server IP Address
for Relay Agent" with our internal DHCP server.

However, the PPTP clients are constantly being given IP's from the range listed in:

"IP Address Assignment for Dial-In Users (When DHCP Disable set)" under VPN and Remote Access/PPP General Setup.

We can't clear this field.

Any ideas would be welcome!

Cheers,

James

For anyone else who stumbles across this post, here is the official answer from Draytek support:

Hello James,

Thanks for the email.Internal DHCP server would only assigns the IP
when VPN is terminating on it.If router is acting as VPN server then
you can't make DHCP server to pass the IP addresses for remote
client.This default behavior with draytek router & we can't change it.

Adam

So, what did you do to resolve this? I have people using PPTP VPN and I need to either have them:

1. have the existing DHCP server on the LAN assign DHCP info to them or
2. enable the DHCP server on the draytek to ONLY be used for VPN clients

It sounds like that the ONLY way to get DHCP for VPN is to have the entire network use the Draytek as the sole DHCP server. I just got off the phone with tech support here and they are still investigating this, but that's currently the answer they are leaning toward.

That will never work for us.
