WAN problems
Once more, incoming mail and FTP traffic were gone last Friday, but this time I could solve the problem by phone – got my son to reset the router. And last week, it happened again but since I was at home, I ran into it quickly and could reboot the router – and look for a reason.
I found it in the log:
Oct 24 01:20:02 Unknown Vigor: 128:41:57.600 wan->lan @S:R=13:1 p 67.195.111.16
Oct 24 01:20:07 Unknown Vigor: 128:42:03.490 wan->lan @S:R=13:1 p 67.195.111.16
Oct 24 01:22:03 Unknown Vigor: WAN 1 is down.
Oct 24 01:22:03 Unknown Vigor: WAN 1 is UP.
Oct 24 01:28:11 Unknown Vigor: --SendMailAlert--
Oct 24 02:14:32 Unknown Vigor: 129:36:36.140 lan->wan @S:R=13:1 p 192.168.0.2,6
and after that, the only incoming traffic passing the router is domain traffic (port 53) and mail (port 2525 in my case). No problem at all for outgoing traffic, just incoming fails time after time. It doesn’t even show up in the log, so the block is basicly on the front end. That also shows by the fact that accessing the secured webs on port 443, all browsers complain that the site’s certificate doesn’t match the one of the site. No wonder: the connection presents the router’s certificate!
Accessing the router from the inside works – but dead slow. Telnet however is fast as ever, so reboot is simple.
This shouldn’t happen in the first place. So I asked the dealer – and he passed information to Draytek – for a solution. Not in, yet…
Spam filter
The spam filter does some checks and the SMTP configuration doesn’t like it:
%%%%%%%%%%% OPCOM 25-OCT-2010 11:38:17.82 %%%%%%%%%%%
Message from user TCPIP$SMTP on DIANA
%TCPIP-W-SMTP_UNRSLVMF, MAIL FROM:<
although this address is set to be acceptable in the SMTP.CONFIG file….Well, not much of a problem, it seems.. I only have to find out why this happens, and what is the consequence.
Another way to be a spammer
Spamfiltering, the Microsoft way – bitten, by itself.
