Heya Folks,
I've had a fun weekend. I was recommended to have a look at this Astaro firewall by a collegue - it looked promising so I set about getting it up and running.
I ended up buying an old Pentium 4 with 1gb of RAM and a 40Gb IDE HDD in order to run it. It had an onboard Broadcom Gigabit network controller and I dropped in a DLink 10/100Mb card for its WAN link.
I connected the WAN link (dlink) to my (NetComm) ADSL router which I put in Bridge mode. I installed Astaro and configured the WAN interface to use PPoE which seemed to connect fine.
However shortly after I found I could not access all of the internet. Originally I thought it may have been a single site down but shortly found other sites were unreachable as well.
As originally I had done some fiddling on the firewall to 'get it right' I thought it may have been my configuration so I re-installed the firewall (this time with all the IPS etc. disabled), however the issue persisted.
For example, I could get to Oracle | Hardware and Software, Engineered to Work Together, Brisbane Times - Brisbane News, Queensland News & World News, PennyTel voip money transfer and Online Shopping - Home but not to www.mynetfone.com.au or Google (for example). This was very perplexing, I could see nothing in the logs indicating anything being blocked.
I changed the DNS servers on the Astaro box to use OpenDNS and tried again - but to the same result. I have rebooted the firewall several times during this procedure with no effect - I even added a Packet Filter rule allowing all traffic, that didn't help either.
So far I am a bit disillusioned, does anyone have any idea what is going on? I could DNS resolve the hosts but I could not ping or reach them over HTTP. Very bizarre.
I have changed back to my ADSL router and everything started working again immediately.
I only downloaded Astaro on Friday and applied the Home License.
