I installed the Thibor12 Firmware on a WRTG54GS v2 (great software btw), but sadly I encounter 1 problem with the Access Restriction. I made two rules : Rule 1) Enable Mac address - in which I use the button â€œedit list of PCsâ€ to add three Mac addresses and allow them access. Rule 2) Block IP address - in which I use the button â€œedit list of PCsâ€ to add the IP range used by the router in my case 192.168.0.0 â€“ 192.168.0.254 and deny them access. When I enable these rules my Internet connection is blocked, of course my pc is one of the Mac addresses mentioned above. Do I something wrong ? Or is this a bug ? I switched from the Sveasoft Alchemy firmware to Thibor12 and did a â€œClear NVRAM, restore factory defaultsâ€. The rules work fine with other firmwares (Sveasoft Alchemy- and the original Linksys firmware).
