enhancing Sonic Wall NSA240 bandwidth for Veeam replication


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).

The slow copy is not only related to the small Bandwith, it's also related on the high respond-time. You send one Packet and then the application wait for the acknowledge from the other side. In LANs the Ping time is only a few milliseconds, over a VPN it goes up till 50 - 200 ms. And this slow the performance really down.

There is a solution from Sonicwall, called WXA. This solution expand the functionality of the soniwall Firewall, specially by sending Files over SMB.


The WXA slow down the respond time and the amount of data. there is a 60 Day trial to check, if this will work for you needs. You need a WXA on each side of the Network.
