Ipsec causing errors on opt inf

[XIII]

since i have done a site-site vpn, my opt inf dont work, clients cant reach the dns server and are being block by the rule below, if i bridged the opt infs to the lan inf everythings fine. the site-site is for the lan infs only not opts.
I have tried other nics, removing and adding nic redoing all rules, same problem.

heres the block rule in the fw log:
The rule that triggered this action is:

@89 pass in quick on ng0 inet proto udp from publicIP to any port = isakmp keep state label "IPSEC: Site-Site Between - inbound isakmp"
