Thanks

did you use VPLS?

I didnt install xen pack.

just routerboard security usermanager dude, IPv6

today I install clean and keep old config. MT seem workin good.(I used 5-10 min. under 70mbit traffic) When I install ssh-key and connect with ssh then MT crushed. hardware info Gigabyte Board ( g33 ) Q6600 CPU 1 GB DDR2 800 Kingston RAM 2 Allied Ethernet 80 GB SATA2 HDD But I have backup 3.11. I'm ...

I have same problem on 3.12. now I try Reinstall 3.12 (all clean instal format etc.)

reconfigure everything and 3-4 reboot later same freeze. This is big bug, I think.

When will you fix it?
