I've been running a virtual Sophos firewall for a while now with no issues. Very recently we've come across an issue where the bandwidth is severely constricted (at least 8x slower vs. same config outside the firewall). This is consistent across linux and windows hosts.
Is anyone else seeing this problem? I've rebuilt one of my firewalls, thinking it could have been an update that cause this, but same issue came up with a base install. Trying everything I can find but am not seeing any difference in performance. I have a potential workaround, but it basically entails circumventing the firewall, which is not ideal.
Any ideas on things to try would be appreciated.
