Hi I need to access a windows XP box that is behind a linux firewall and
a linksys wireless access point, also acting as a firewall.
Proir to adding the wireless access point here is what worked. First I
established an ssh tunnel to the linux firewall with port 3389 on my
local machine forwarded to port 3389 on the XP box. I then launced
rdesktop pointing it to local host, which took me through the ssh tunnel
to the XP box. Worked great. (running redhat 9.0 on my local computer)
I have changed my configuration a bit now. The lan side of the linux
firewall is at 192.168.240.1. It is doing DHCP, handing out addresses in
the range 192.168.240.60 - 69. My linksys wireless access point gets its
wan side IP address from the linux box. The lan side of the access point
is 192.168.240.11, it does not do DHCP. The boxes inside the linksys
have static address in the range 192.168.240.20 - 29. I have restricted
access to the wireless access point to only computers identified by
their IP and MAC addresses.
The specific box I need to access remotely is 192.168.240.22. I have
changed my ssh command to the following :
ssh -l charlie 209.250.xxx.xxx -L 3389:192.168.240.22:3389 .
In addition I have set up a rule in the wireless access point to direct
any traffic on port 3389 to IP address 192.168.240.22.
Unfortunatly, this doesn't work at all. In fact when I simply ssh into
the linux box I can't even see the wireless access point or any boxes
inside. All of the boxes inside the wireless access point can see each
other and can access the internet, but none can see the linux box.
Any ideas would be appreciated. I am needing a secure solution that
would still let me get to the XP box remotely.
Charlie
