Why no DHCP packets on ports 67 / 68 from the VPN server?

Hi,

I have set up the VPN server on XP.

After a lot of work adjusting firewalls and router settings I can now log in from an Android phone! Hurrah!

However I need to set the Virtual DHCP mode in the server to do this.

If I do not set Virtual DHCP I get a DHCP failure in the log files - and no connection.

I then put a DHCP server on my XP machine, and fully tested it.

However still no luck!

So I installed Wireshark, the network packet viewer. If I turn Virtual DHCP off, I do NOT see any DHCP request from the VPN server during a remote connection process.

I just get the DHCP error in the log file.

So: can the VPN server really use an external DHCP server running on the same XP machine?

Thanks!

If you bridge the virtual hub with you're local lan the client will get it's ip address from the local lan's dhcp server (whatever that is).

Ah, it seems that I have missed a vital step ... back to the manual ...

Many thnaks!
