Hello Community,
I'm migrating from a SG550 (UTM) to a new XGS5500 (SFOS 19.5). Both firewalls connected to the same ISP. If I connect to the UTM via L2TP I can copy a file via CIFS with around 5 MB/s, which is almost equal to the bandwidth of the client. If I connect to the XG (same client, same internet connection on client side), I can only download with a speed of 1 ~ 1.5 MB/s. Other test users report the same problem.
I did some tests with different MTU sizes on XG (reduced from 1410 to 1320 in L2TP configuration), the same on the Windows L2TP Adapter from 1400 to 1300. All combinations did not speed up the CIFS download.
Has anybody the same issue and solved it?
