Hello all,
I've run into some strange problems while trying to
operate Gauntlet 5.0 on NT4/sp4.
My setup is pretty minimum: NT4/SP4, Gauntlet 5, two NICs,
DNS on the machine. Subnets (as an example) :
trusted 194.219.12.0 netmask 255.255.255.128
untrusted 194.219.12.252 netmask 255.255.255.252
Transparency is enabled on both NICs. All IPs on both
sides are legal.
Overall, the status is that I have full functionality
from inside (trusted) going outside (untrusted) but can't
get results going the other way round (from outside into
the internal, protected, network).
What I need to do is allow:
trusted users: http,ftp,telnet,lotus notes access
untrusted users: access a designated internal web
server hosting several virtual www
servers, and access the internal
lotus server
As far as accessing the internal web server is concerned
the only solution that produced *some* results was allowing
the untrusted users use the http proxy and handing-off the
request to the internal www server. BUT, Gauntlet somehow
modifies the external user's packets and thus the www server
cannot determine which virtual server the user is trying to
access.
I've tried all possible combinations I could come up with
and still no result. I even used packet screening to allow
ALL ports to and from the web server (and the lotus server
as a second test) and this DIDN'T work either !!
Does anyone out there have a similar setup ?
I would appreciate ANY suggestions as I'm all out of ideas.
Regards,
Dimitris.
