guys i got linksys vpn router at work. i got sentinel at home. i got connection to office vpn router successfully, i can access printer at work through vpn but cant access XP Pro computer which is at work. I can ping to XP computer though VPN but cant access shared resources on it. I can only access resources on office XP computer if i turn off its firewall. Can anyone tell me what ports or anything else i can allow on XP firewall to gain access to those resources without turning whole firewall OFF.
