I have been playing with this for a bit now, and dont want to go for my standard hit and miss routine any more!
For the purposes of this exercise, I have 1 global IP - I want that to connect to 3 servers
This should be simple;
ip nat source static tcp insideip1 80 outisdeip 80
ip nat source static tcp insideip2 25 outsideip 25
(i may have left something out of that, but you get the idea - this is all working fine)
Now, the problem is, I want one of those to go to a PPTP server - how do I get GRE to map the same way?
I know I can; ip nat source static tcp insideip3 1723 outsideip 1723 - but that isnt working, and I am assuming the problem is GRE
thanks in advance
