RRAS VPN Setup on widows server 2003, behind a firewall Watchguard

HI ALL

could some one help me troubleshoot my problem with rras vpn setup server.

our network has two servers, both are windows server 2003 , and are domain controllers.  I have setup rras on one of the servers with a dedicated nic for it. I have opened up firewall which is provided by Watchguard router. we only have one public ip. on the firewall I have opened up the port of pptp and assigned the host address as the ip address of the nic I am using for rras. ( I don't think , this device watchguard, has explicti natting available).

When I try test by creating a vpn connection using a computer from my home it hangs at verifying user name and password for a bit, then gives the error message ' error 691: access was denied becuase the username and or password was invalid on the domian.'

I have gave the user account I am using to connect access as allow in the properties of AD for dial and remote access connection ( something like that, i don't remember the name of the option /tab).

am I mising something really obvious here. how do I troubleshoot this issue and hopefully resolve it.

you must allow also GRE protocol on your router

This really depends on which watchguard you are using. If you are using a firebox and not the soho. you can setup a direct one to one NAT with out a prob.

Which Watchguard are you using?

when i specify pptp as the service should it not automatically take care of both the tcp port and protocol on the firewall.??

I actually did try creating my own service and specifying the the rras port as well as protocol, it gave the same result
