Here is my configuration. My new DIR-601 router is connected this way. Wan port to Isp modem, LanP1 to a Win7 Pc1, LanP2 to a Linksys router, DHCP diisable using the 4 LAN ports as a switch in wich 2 Pc are connected 1) Win Xp PC2 and 2) Ubuntu 10.04 PC3.
The problem is , I can not access internet behind the telesyn switch, PC2 and PC3 have no access to Html servers on the Wan, except if I define PC2 or PC3 , only 1 allowed at a time, as DMZ. If I plug PC2 or PC3 directly in DIR-601 port everything is ok.
Why DIR601 port connected to a switch does not work the same way than conected to a PC. Any solution to give Internet access to PC behind a switch ?
NB: This work if I replace DIR601 with DIR620 router.
