I just started using dd-wrt on my wndr3700, but now all my incomming connections to a server inside the network gets the same source ip as the router. How can I change this back so I get the real source ip?

I have a pretty common setup with a fiber modem and the wndr3700 as distribution.

Tell us more about your configuration. How did you set up port forwarding exactly? –  David Schwartz Nov 8 '12 at 8:19
    
@DavidSchwartz: I just used port range forwarding in the web interface. This is a dump of the nat table: pastebin.com/F2U0QW16 –  Lasse A Karlsen Nov 8 '12 at 8:25
    
What's the SNAT rule for? –  David Schwartz Nov 8 '12 at 8:29
    
I don't know, I haven't added it. Must be something generated by the web interface...? Remove? –  Lasse A Karlsen Nov 8 '12 at 8:34
    
MASQUERADE 0 -- anywhere anywhere probably isn't helping. –  Xyon Nov 8 '12 at 13:46

Put the server in a DMZ. Did your port forwarded services receive publicly sourced IP addresses beforehand?
