vpn (vpcn) connection problem

Ron Bombard — Sat, 27 Oct 2007 11:35:45 GMT

Hi!
I'm using Kubunto 7.10

I'm using KVpnc to connect to my work cisco PIX vpn.

I want to rpc to a win2003 machine.

It says I'm Successfully Connected.

But... nothing works. I understand it will screw up my local web browsing and what not, but while connected to the vpn, thats fine.

But I cannot connect to anything on my work vpn.

If use rdc, and it says "Connection attempt to host failed"

If I try rdesktop, is says "No Route to host".

the remote vpn is 66.195.66.65 (cisco pix vpn)
my local ip is: 192.168.2.1 (vulcan)
my gateway to the net is: 192.168.2.34 (vpn router)

On my router I have the following ports forwarded to 192.168.2.1: 22, 5900, 5901, 3389, 500 plus others

This is my route output:

ronb@vulcan:~$ route -n

I assume maybe my route is screwed up somehow? any ideas?
can someone point me in the correct direction? I've been working on this for a week now to no avail.

Thanks Much!
Ron

infact i did not really understand your problem scenatio..but

did u notcie the "dropped" cipsec0.?

Please check with your network support guys too if any errors reporting from switch ports. What about the speed&duple settings at both ends..

I'm sorry for not being clear.

My problem is, I connect the vpn, and then cannot connect to any servers ON the vpn. The vpn connects, asks my User & Pwd, then reports a successfull connection.

But I cannot RDP to any servers. I can from my Winblows machine though.

NO, I didn't notice the dropped TX packets. What could cause that? a firewall issue maybe? I thought all I had to do was forward port 5900 for the vnc, and 3389 for RDP. The same forward rules I used for my windows m/c.

Hi,

Are you able to ping the servers,once VPN is connected.If u able to ping u can able to access it.Check with ur crendentials having power to take RDC on the Domain on which u r connecting through VPN.

Regds,
