Sophos UTM 9.406-3 released

Since installing this update, my WAN interface (DHCP, plugged into a cable modem) is down.  I tried to set a manual address (the last one I had) to no avail.  

Anyone have a solution?

Thanks

You may be a victim of the change from a few updates ago. Check your MTU for the WAN interface to see if it changed from 1500 to 576.

Thanks Ryan,

That it did.  I switched it back to 1500 to no avail.

EDIT: I see there is more to it than changing it in the GUI.  I'll wait for an update (unless there is a better solution).  I'm still doing my research on this based on the MTU problem.

From what I saw, it involved SSH.

Yeah.. I tried what was described in https://community.sophos.com/products/unified-threat-management/f/52/t/79288  

Unfortunately, that didnt help.  My MTU stays at 1500, but the WAN still stays down (even after issuing an ifconfig eth1 down, then ifconfig eth1 up).

Reboot didnt help either..

Thanks

I followed those instructions for a dynamic Comcast line and luckily it worked great.

I may still reload with the previous release though because I prefer not to hack the OS.

As a Sophos Partner, it's disappointing indeed but they still make the best security products for our customers.

This is exactly why we don't update firewalls right away unless a fix is absolutely needed.

Good advice.  I'll try again and maybe it will work this time.  I thought that all I had to do was take out the mtu part from the config file and restart the interface.  I'll read it again and try soon.
