Remote Desktop bombs out when i connect over VPN

[Guest]

Hi Guys,

My knowledge about networking is very basic since i am a software guy and my
question is VPN related, when i am remote desktoped into my home machine from
outsite the network and then onnect VPN to my office network, i am kicked out
of remote desktop connect and can not connect back to the machine over remote
desktop as long as the VPN is running, if i disconnect the VPN and connect
again, i am in. Here are the details:

Home machine : Windows XP Pro.
LAN TCP\ IP properties : Optain an IP automitically, Obtain a DNS
automatically.
Home network Setup: i have a comcast router\ filewall which bring in
comcast internet connection. From the comcast the cable to my lingo ( voice
over ip) router. From the lingo router it then goes to my Computer.

Comcast router gives out IP in the range : 10.1.10.**
Lingo router in the range : 172.125.25.**
My machine is configured to obtain an IP and DNS automatically from the
lingo router and it gives it 172.25.25.2 all the time.

I configured my comcast and lingo router to pass on the Remote desktop
request comming from the public IP to my machine and it works great. But the
problem is that after i Remote desktop into my machine from outsite the
network, if i connect to the VPN of my office network then remote destop
bombs out and i cannot connect to my mahcine from outsite any more. After the
VPN is connected when i do an ipconfig of my machine, my machine now has two
IP addresses one that the lingo router assigsn i.e 172.25.25.2 and the other
IP 192.168.168.* that my office DNS server assigns and i think this is where
my comcast and lingo routers get confused and not connect request comming for
remotedesktop to my machine.

so the question is how can i configure my comcast\ lingo router or my
machine so that even when my home machine is connected over VPN to my office
network i can Remote dektop into it.

waiting for an answer.

thanks

Your problem is that your VPN is configured to route all traffic through
the VPN to your office network. If possible (your company may not allow
it)
you need to configure the VPN so only traffic destined for the office
network
goes through the VPN and all other traffic goes to the internet. The reason
your company may not allow this is it creates a sneak path from the internet
to your office network that bypasses the company firewall.
