Site to site vpn

Hi everyone I have got issues with site to site VPN,

My pcs are able to vpn to the other site but the pcs are not able to use the internet. why.

This is the NAT configuration

ip nat pool NAT-TRANSLATION 172.28.15.113 172.28.15.113 prefix-length 29
ip nat inside source list 103 pool NAT-TRANSLATION overload
ip nat inside source route-map SDM_RMAP_1 interface FastEthernet0/1/0 overload

This is the ACL configuration.

access-list 102 permit ip 172.28.15.112 0.0.0.7 host 192.168.228.81
access-list 102 permit ip 172.28.15.112 0.0.0.7 host 192.168.228.82
access-list 102 remark SIBS
access-list 102 remark SDM_ACL Category=4
access-list 103 permit ip 10.11.0.0 0.0.255.255 any


Thank you.

Try defining your inside and outside interfaces:

ip nat inside fax/x/x
ip nat outside fax/x/x (looks like for you it's fa0/1/0).
