i use RB951-2n as a ppp client with bridge modem for dsl internet and there is a strange issue:
assuming i have pppoe-out on ether1 and i have changed nat rules to ppp interface everything works but some web sites cannot be opened dunno why BUT when i change default drop filter rule and add in interface pppoe-out everything works ok. is this some problem or i have something else misconfigured? do i have to add in interface to default drop rule or is it wrong?
can you post your configuration? if some websites work and others don’t it sounds like a MTU issue. is it possible that you drop ICMP in the situation where it is not working?
