Hey everyone,
I've got a bit of a weird issue with my Astaro that has me stumped.
Background:
Recently we started testing the site to site VPN capabilities of the Astaro with an eye to expanding these units out to our branch offices. The branch unit is an Atom 330 w/ 2GB RAM that has been solid since we purchased it around six months back. The branch itself has maybe three PC's in sporadic use, a printer, and a Debit Machine, well within the capabilities of the little Atom. The unit has been running on a semi-commercial ADSL line for about 3 weeks before we started encountering problems.
The problem we are having is that throughout the day the unit will randomly lose it's connection to the internet. By 'lose', I mean that all traffic going beyond the confines of the office, either Internet or VPN, stops flowing. Once it drops the only way we can get traffic back is to power cycle the unit.
When this is happening the box stills appears to be up. I can ssh into the box and watch the system as it happens Webadmin says the link is up, the router & network card both show the link is active. There are no unusual spikes in system load, no errors show up, nothing. In short the box appears to be functioning perfectly, it's like test pings, DNS queries, everything goes out the external interface and stops dead.
I've replaced the impacted network card as I've seen them break in this exact fashion but even after replacing the card it's still doing this. And I highly doubt that I'd get two cards fail in exactly the same fashion. Even the cables were replaced 'just in case'.
I'd blame my ISP (Telus) as their method of allowing devices onto their network is somewhat odd, they require all devices behind their ADSL to 'register' the device MAC with their DHCP servers, and failure to register will cause exactly what I'm seeing. In this case however, I've been through the registration process, my ISP has confirmed it's done correctly, we're getting the IP we're supposed to, they can't see any issues with their gear, and the cheapo netgear router currently sitting in place of this Astaro unit has maintained a rock solid connection over the past week.
So what am I missing? The hardware appears fine. Astaro software appears fine. ISP's gear seems fine.
