TCP connections don't work on MLPPP link only for Linux box

Hi,

my customer have two ADSL with MLPPP enabled. I setup PPPoE with two ethernet interfaces (without master ethernet on RB2011).

The connection work without problems with Windows computers. Instead from Linux computer only TCP connections are always in SYN state. UDP, ICMP, etc works.

I suppose that is MTU related problem, but I don’t have any idea how to resolve.

I tried to change MSS into Mangle Chains without success.

Another thing. If I disable an ethernet connection, all work perfectly.

Can anyone help me ?

Hi,

a reply from Mikrotik team is appreciated.

I don’t understand why with a single line connected the MLPPP connection it works with Linux boxes, instead with two lines connected does not work.

And, here I’m very angry, with Windows boxes there aren’t any type of problems.

I have solved with PFSense. The MLPPP connection work fine now. I’m very sorry that with Mikrotik board don’t work.
