PPPoE disconnects each hour.

Hi,
each hour after I have restarted my pfsense router, the PPPoE disconnects! I see this in the logs:-

Mar 5 08:05:02 pfsense mpd: [pppoe] LCP: rec'd Terminate Request #38 link 0 (Opened)
Mar 5 08:05:02 pfsense mpd: [pppoe] LCP: state change Opened --> Stopping
Mar 5 08:05:02 pfsense mpd: [pppoe] LCP: phase shift NETWORK --> TERMINATE

Mar 5 08:05:02 pfsense mpd: [pppoe] up: 0 links, total bandwidth 9600 bps
Mar 5 08:05:02 pfsense mpd: [pppoe] IPCP: Down event
Mar 5 08:05:02 pfsense mpd: [pppoe] IPCP: state change Opened --> Starting
Mar 5 08:05:02 pfsense mpd: [pppoe] IPCP: LayerDown
Mar 5 08:05:02 pfsense mpd: [pppoe] IFACE: Down event
Mar 5 08:05:02 pfsense mpd: [pppoe] exec: /sbin/route delete 0.0.0.0 94.30.127.

etc

Then it re-connects.

I am running pfsense 1.2.3 on a Soekris box with a Draytek Vigor 100 ADSL2+ pass-trough modem.

This has worked fine in the past but I can't be sure when the problem started. I did used to run m0n0wall for several years before
I switched to pfsense a few weeks ago.
Cant be sure if it is my ISP, ADSL24 with murphX dsl, or my setup here.
Anybody else seen something similar?


Thanks
