I have an 871 router configured for a few vlans. Two of the vlan have access to the internet with no issues but the third I cannot get to communicate to the internet. The two vlans (3 and 4) are set to trunk and the vlan (501) is set to access. I don't want vlan 501 to be able to communicate with the other two (3 and 4 access internal items across a vpn).

I have atatched some of my config relevent to this issue. I am sure I am doing something stupid but can't pin point it.

Any help would be greatly appreciated. :)
