Silly question time

Ok here is where the jeers from certain corners will come flying, but
with the hope of a sensible answer here goes...

What ports are generally used for VPNs? I'm asking about standard
ports not for some special exotic set up....

TIA

Try this as a starting point...

The magic phrase is "well known ports", a term used in the RFCs.
However, I expect there are a *lot* of exceptions.

Ta very muchly it's given a few pointers to try, instead of just
putting the neccesary IP into the DMZ to get in....

& no the IT support don't know (believe it or not, but we are talking
about the support group who said Melisa wouldn't get in...guess what
it did)

If you have unlimited access to the PC (i.e. can instalkl software) then get
the old sysinternals stuff from www.sysinternals.com (it redirects to an MS
page) and that "may" show you which port its using...

Pity about that, I have access to the hardware firewall but am not
able to install any software to the relavent PC

Some (e.g. winXP using PPTP) require TCP port 1723 *and* the GRE
protocol (GRE is not a port number on top of TCP or UDP, it is protcol
number 47 direct on top of IP, in the same way TCP is protocol 6, or UDP
is protocol 17).

Some (like openVPN) can run over tcp port 443 to "confuse" most
firewalls into thinking it's https/ss traffic.

For IPSEC you'll see UDP port 500 *and* ESP and AH IP protocols (50 and
51 like GRE was 47).

Others have mentioned cisco's offering.

Then you get down to the level of sneaky gits who tunnel IP on top of
DNS queries to get free use of wireless access points :-)
