Hey guys I am not able to play CS:S w/ my router configured. I went to steampowered.com and check which ports need to be set up. I called my Router Provider (Belkin) and they walked me through opening up ports so I could play (Retrieved ports from steampowered.com). After rebooted router/cpu/ect. I tried to run steam... Again I get the exact message. Also I check steampowered.com for the list of routers that do not support steam period! But my belkin was not listed. If any 1 has had similar issues and has retrieved a(n) resolution please help!! NOTE: I have done my homework.. but there maybe something I am missing. Also When I put in ports to be open (e.G 7500-8000) I am not sure if I put them in right. I am at work right now, but I will upload a SS with a detailed picture! Thanks
