I'm having a issue with Tomato firmware on my Netgear WNR2000v2 router (and Linksys WRT54GL).
The problem is related to RTSP communication, I have an IP-tv box that needs real NAT translation to be done to the IP-packets payload.
Do someone know if this is possible, either with DD-WRT or Tomato, and if yes how?
Standard iptables MASQUERADE and/or SNAT/DNAT only seem to alter the IP-packets header, source/destionation address, so when I use Wireshark to trace the packets sent out WAN I can clearly see in the RTSP SETUP packet that it states "destionation:LAN-IP" of the IP box. That makes obviously streaming impossible…
