Hi, Currently Iâ€™m using Linksys WRT54GL and Tomato 1.06 (I might also flash different firmware if this would solve my problem below) My ISP who gives me the same IP address to two different MAC addresses â€“ so I can use those two computers (Desktop and Laptop) â€“ but they can not work at the same time because of that. Hardware configuration looks like that: Ethernet socket --> WAN port on WRT54GL LAN port on WRT54GL --> laptop I can not split/share this internet connection properly. After making settings (details below in the post) I can ping to www.google.com or to any other website. I can do it using router feature Tools/Ping or if I do pinging from laptop. It would mean that I have connection to external world via this router. BUT any www or any telnet or any ftp do not work â€“ nothing â€¦. My goal is to share the Internet Connection to laptop and desktop in a way when both could work simultaneously. INTERESTING thing is that when I use ICS (Internet Connection Sharing) on my desktop with AnalogX (proxy software) â€“ both computers might work simultaneously without any problems. Configuration looks here like that: Ethernet socket --> router (LAN port) --> cable to NIC @ desktop and - - > laptop via WiFi connection. Of course disadvantage of this solution is that desktop has to work all the time. The goal is to configure network in a way when Router will share internet connection (and not desktop via proxy) I do not know what protection is on ISP site (if any) â€“ but Iâ€™d like to try to find walk around. I red about possibilities for ISP to discover that user is sharing connection â€“ but also about different ways to walk around it and hide the fact. All articles I saw were saying that it is anyway possible â€“ but I couldnâ€™t find instruction. Maybe this is only wrong setting in my router and Tomato firmware. Anyone could help with that problem? My HW configuration looks like that: WAN MAC Address 00:07:C6:57:C1 (This MAC is registered to ISP) Connection Type DHCP IP Address 172.25.5.165 Subnet Mask 255.255.255.0 Gateway 172.25.5.2 DNS 192.0.2.2, 220.127.116.11 MTU 1500 LAN Router MAC Address 00:14:BF:6A:C3 Router IP Address 192.168.1.1 Subnet Mask 255.255.255.0 DHCP 192.168.1.100 - 149 Iâ€™ve tried to change TTL to "none" and to +1 â€“ didnâ€™t help Iâ€™ve tried to set smaller MTU Regards D.
