IPTables redirect back to internal IP

Aha!, think i have it cracked.

adcburke,

I might need to use this in the future.

So that I understand...is the following diagram accurate for the iptables rules you listed?

  [Internet]
     |
     | traffic to x.x.x.78
     |  V
     |  V
     |
 +--------------+
 | nat/iptables |--------[192.168.100.250]
 |    router    |
 +--------------+
   |eth1 
   |(x.x.x.74)
   |
---------------
       |
       |
      [general]
      [users]

Is how this is setup. anyone connecting to the network end up on the 1 subnet

I'd consider bringing your DNS server in house if you have such an unprofessional and uncooperative provider.

Haha, yes that is the ultimate goal but we are not prepared for that yet, this is a bit of an interim solution
