i am new to networking. read some articles but cant seem to figure out how to let internal network get internet access.

i have 2 server. S1 has 1 nic card with static ip . S2 has 2 nic card. 1 with static internal ip other with external ip. all cables from server and router goes to a switch

s1 is dc,dns, dhcp and file server. s2 is a workgroup computer, want to use as a gateway. i can get internet on all clients when i use TMG 2010 evaluate version.

i want to give internet to internal PC with RRAS without using TMG. i tried RRAS NAT translating option. s1 gateway is set to s2 address but i cant connect to internet.
