Hi,
We have 2 sophos UTM SG115 (box A and box B) which are connected by a VPN link on 2 different locations.
Both SOPHOS are of the same revision, 3 and has the latest firmware updates (9.706-9).
A box is behind a 200 Mb symetric optical fiber acces with SFP port directly connect to the optical fiber.
B box is behind a 800Mb(d)/400Mb(u) optical fiber access, behind the ISP box.
Testing B speed on the internet, it can reach 250Mb(d)/343Mb(u).
Testing A several times at different schedules, while acheiving 190 Mb(d), it can't exceed 100 Mb(u), like it has some stop, some blocking.
Testing A has be done directly on the SOPHOS LAN port diconnected from the office lan.
An ISP technician came at the office, tested the link in same conditions, with a PC directly connected to the LAN port of a basic entry level firewall router, it reached indeed the throughput of the internt acess (190 Mb(d)/189 Mb(u)), so the internet access hasn't any blocking.
Our SOPHOS integrator, talked about some blocking on some SG 115 revisions, but as they are of the same revision, this explanation doesn't match.
Any idea or suggestion?
Thank's for help.
Olivier
