Problem with MRU? - MT3.23

Fri May 08, 2009 9:27 pm

Hi

I've noticed there's a possible minor bug on MRU setting for PPPOE connections.

I create a new PPPOE connection and force MTU and MRU to 1480 - This is necessary as the maximums for the WiMAX connection over which the PPPOE's connect.

Once connected, if I go to the Status tab the software is reporting MTU correctly at 1480 but the MRU seems to have reverted to 1492.

In this state I cannot connect to most sites as the MRU is having a negative effect on the connection's ability to exchange large packets... simple things like ICMP etc work fine.

To fix the problem I've configured the profile to not change the mss dynamically and I've added some static mss rules forcing the maximum segment size down to 1480-40 (1440)

Am I missing something on ROS or is there no other way to handle this and therefor a bug which exists in the current version of ROS.

Thanks

Most definately a bug of some sort...

Does the same on RB230 and RB433 - Even in MT3.24 pre-release!
