RB1100: no internet after reboot

Hi there,

recently we has RB1100 installation at our client site. The very unusual problem is no internet after the router reboot.

for temporary problem solve, we did router reset and reload the config (RSC). But again, no internet after the router reboot.

to go to the internet, the router connected to DSL line and do pppoe dial to the provider.

the only different that we can see between after reconfig and after reboot is /ip firewall mangle.

when doing router reconfig, we discover there are two dynamic lines for the DSL that contain ‘change MSS’ on line 0 and 1. BUT when the router reboot, this line moved into the last lines as we also have some rules on /ip firewall mangle.

Is there anyone that having similar problem ?
if so, how to solve it ?

If you se, its not changing the packet size (counting 0). There have to be something else.
