Hi there,
First time poster. Recently I have implemented a Sophos UTM VA on Hyper-V 2012 R2 in a lab.. Recently I have started noticing that certain sites (ebay.com.au) are not currently loading within the browser. Would return a sophos website timeout error. In an effort to troubleshoot the problem, I have:
- Re-installed the UTM OS - Version: 9.403-4
- Put a bare bone firewall rules (Any Host - Any Service- Any Dest)
- NATted it.
- DNS Forwarder
- DynDNS Setup.
- Enabled IPS. (All Features)
- (To Test the ISP) Plugged a laptop directly into the NTD (AUS NBN) - No Problems.
- NOTE: Web Filtering is Disabled.
I can browse all other sites, and I can nslookup these hosts. I have checked the Firewall Log, which is showing nothing. The IPS log shows nothing. I performed a tcpdump on the interface and i can see the DNS traffic.
Out of idea's and Stumped.
Michael.
