Hi guys!
I am facing an annoying issue...
For some reason my WAN interface reports as UP but with link error
When this happens my backup 3G connection takes over, after a while WAN is up again and I get a ton of emails that link is down/up again
I have searched the forum and found other issues like this and I saw that the solution was to fix the port speed on the ISP modem with the same speed as the UTM port.
However my situation is different and I don't know if something like the above applies here.
My connection is this: Phone cable-->ADSL modem (router in bridge mode) -->Sophos WAN interface via Ethernet
The WAN interface is PPPOE
The thing is that the led on the Modem which indicates if it is synchronized with the broadband line is on, so the modem does have connection
However since UTM constantly goes to link error I keep losing Internet connection
Two nights ago I performed a factory reset in Sophos (BTW a note that factory reset erases all logs would be a good reminder in the GUI - I would have saved that 15 month worth of logs before reset...)and restored configuration from a backup. Things seemed to stabilize, so thought I got this fixed.
Yesterday evening it started the same thing. And additionally I had broadband disconnects on the Modem (about 130 according to my ISP). I performed a factory reset to the modem, set it up again and things again appeared as stable.
This morning I saw there were about 20 more up/down emails on my mailbox (the 3G kicks in when this happens) from 6 a.m. until 7 a.m.
From that time on it has been stable...
Do you guys have any ideas?
Which log should I check when this happens?
Does the port fixed speed apply to my situtation? If yes where do I set the speed?
Thanks a lot in advance
