Hi All,
Long time follower, first time poster!
Our company has been using Sophos gear for quite some time and have had a good run, but recently we had a deployment at a doctors practice that would not allow HTTPS traffic flow,
The network was based on an onsite domain controller and a Telstra ADSL Modem-Router, (the router running the DHCP)
We swapped the client over to an XG 85 with an ADSL modem in bridge mode. - Connection is fine, speed is fine etc..
Anytime any workstation on the lan tries to login to any https webpage it will stall and timeout, we can browse and use sites like google.com with no side effects, but as soon as we try to login to any site it will time out.
Heres is a list of the things we have tried;
Lan to WAN firewall rule created
No subscription services are on/have toggled between off and none, allow all etc.. but no effect either way.
HTTP & HTTPS scanning is off
Micro App Discovery has been turned off via the console
Factory reset done multiple times
Firmware upgraded from 16.X to 17.X
As soon as we plug back in the original Telstra ADSL modem it works flawlessly for all websites & services.
Will open web landing page, but as soon as any sign in is required it appears to block all traffic,
Ping will run continuously without interruption to any address
Have made sure the 127.0.0.0 is removed from the DNS page, have tried using google dns’s and then Telstra’s with no change.
Some machines on the network work for a short period then revert to the same issues.
Have tried static IP & DNS and also allocated for the LAN workstations.
Any help would be greatly appreciated,
Cheers
