I own two XG230 in HA with fw 18mr3, since I switched from MR1 to MR3 the speed of vpn is much improved (from 12mb to 60/70mb).
VPN is configured as ssl tcp on port 8443 with comp enable
The wan it's fiber 100/100,since I have updated the firmware I saw a drop in speed during the day even until late in the evening, arrive at an upload of 0.5mbs and download of 7mb, even if the wan was not saturated or overloaded
Thr test it's in SSL TCP except the highlighted one I did in IPsec
Early this morning I did the test between TCP and UDP
I can't understand what it could be
maybe the BUG ID it's NC-62448 -Core dump on Snort
and my case it's 03271059
