This topic was raised by someone else about 1 year ago - but I did not see any solution(s).
I am setting up a 2-tier firewall system and it all works EXCEPT (just like the other guy) I cannot figure a way to VPN into the 2nd tier. The 1st tier is no problem (allows remote management of my DMZ servers) but I cannot figure out how to connect to a server on the 2nd tier. The 2nd tier "RED" blocks (by design) any "initiated" contact from upstream.
Only success so far is to put 2 NICs in my 1st tier VPN server (only open VPN ports) and assign one of the NICs a 2nd tier IP. NOT GOOD!!!
Would be great if I could port forward from 1st to 2nd tier, but cannot get around that upstream restriction.
I must use 2-tiers. Final objective is to VPN to the 2nd tier (that way I can still control DMZ servers).
Answers, hints, clues ???
