I have a symmetrical 15 Mbps line at the office and another at the DR site. I have a VPN between the two. Office has a Sonic Wall NSA 240 and the DR site has a TZ 170. I am only getting about 1.5 Mbps throughput using Teracopy to a mapped drive on a VM at the DR site and using FileZilla (DR site is server, office is client). I am being told I should be getting at least 50% or more of the 15 Mbps bandwidth. This is crippling my Veeam replication.
Any suggestions on tweaking the firewalls to achieve the bandwidth I am being told I should be getting? Is it possible to achieve up to 7.5 Mbps in this set up? Even 4 Mbps would be sufficient since this line is also used by some users (minimal impact though).
