Remote Branch reconfiguration

[Jon <jono29 () gmail com>]

Hello,

/First of all apologies if this is the wrong list./

I have, or rather had a few site to site vpn's set up. This is not my 
setup, but rather its

inherited . I have two remote branches terminating on one pix at the 
head office and another

vpn terminating on a different pix, also at the head office. On these 
tunnels I pass RDP

traffic aimed at a Term server. From the termserver, there is a seperate 
route out to the

internet for all hosts. The models of pix are 501's. I am led to believe 
that you can only

have a maximum of two tunnels terminating on any one 501 firewall. I 
presume this is why two

501's were used. Now to my issue: For reasons best left unsaid, the adsl 
line on the pix

with only one site to site vpn configured has had the line cancelled. 
This is causing me a

lot of grief from a customer and bearing in mind I dont know that much 
about cisco configs I

am at a bit of a loss of how to get the third and presently cancelled 
remote branch securely

connected to my head end. Would it be possible to configure an access 
list on the pix that

allows RDP traffic from the remote site - if so, then how? I have an 
Internet connection

available to me at the remote branch, I just need to know the best way 
to integrate into the

only available pix that is remaining.

To summarise:

Remote Branch A &    VPN        Head END PIX 1
Remote Branch B

Remote Branch C        VPN        Head END PIX 2 (Now Cancelled)

Possible:
Remote Branch C        RDP (3389)    Head END PIX 1


All the Pix's are 501's. Trm Server is Windows 2000. Clients are XP.

I hope this makes sense - any help much appreciated.

Regards

J
