My friends and I setup a LAN with a Linksys 5-port workgroup switch using SWBELL DSL. My friend's computer has the DSL software installed and he uses ICS to share his connection. We have 2 other computers connected to the switch, but the 2 other computers can't access a lot of websites but the main computer can access everything. Is there some kind of firewall preventing the other computers from accessing websites? How can I fix this. Thank you in advance
