Hi,
Attempted an upgrade as per subject for a client.
We experience the following issues:
1. Random issues with traffic flow. Some servers could ping across the router to the internet randomly.
-- This turned out to be fixed by disabling hardware acceleration.
2. IPSEC Site-to-site VPN with policy routing (to AWS)
-- No traffic would flow across the IPSEC link until i enabled NAT. Using conntrack to identify the sessions - it looked correct and matched. Firewall policy test evaluated as expected. I tested with ping from the firewall, and that got through to the remote network ok.
3. Remote users connecting in with L2TP VPN
-- On V17, this was rock solid. On V18 the VPNs were randomly dropping. There were LCP errors in the log as well.
4. Voice quality - Phones connect (routed) across the Sophos between two local LAN segments.
-- On V17, this was fine. On V18, it sounded like there was constant very low packetloss, or perhaps the occasional packet experiencing jitter. It sounded like there were weird compression artifacts or something.
We've given upSophos engineer rolled back to V17 and all these problems seemed to go away.
Googling around shows we're not the only ones experiencing these weird problems.
Is this typical for the 'upgrade pain' to V18?
Is V18 ready for production use?
