So i`ve made a config in attach

 


So all this conf was made to allow internet acces from 10.x network with 10.0.1.1 dns servers.

It works great only with ping or dns requests. But all TCP connetcions drops and I can`t figure out why. Test PC can`not acces internet from 10.x network (

 

What is wrong???

stateful-firewall {
rule allow_tcp {
match-direction input-output;
term 1 {
