Slow file copy - SonicWall NSA 2400 Firewall and VPN
I'm configuring a new server and firewall locally before I install it in the datacenter, and I'm having problems with file copy speed using VPN. I know that I don't have to use VPN locally, but the point is that I'm trying to configure the server as if I were doing it remotely. Here's the basic setup:
- Gigabit switch - desktop (that I'm trying to configure from) and SonicWall NSA 2400 are connected. Thus, firewall and desktop are on the same subnet (192.168.0.10 and 192.168.0.200).
- Behind SonicWall is a Dell PowerConnect 2824 Switch in managed mode. I've configured it with VLAN so that the DMZ and LAN networks can be segregated using the same switch, and thus only 1U of rack space.
- Behind the PowerConnect switch is my server.
All connections are gigabit. When I VPN into my firewall (using SonicWall VPN Client), pings respond in < 1 ms. However, when I copy files, the transfer rate is ~ 10 kb/s. If I physically plug my desktop into LAN on the 2824 switch (thus bypassing the firewall and VPN), file transfers fly. This obviously won't be the case when I'm remotely configuring the server.
Any ideas? Thanks in advance.

To understand your description, you never had DHCP configured on the Sonicwall for GVC connections, right? At least, that's how I'm reading it. If you haven't configured your Sonicwall to provide GVCs with an IP, then it's not going to connect properly. As you said, the GVC will show disabled.
ASKER
Yeah, DHCP was not enabled for my VPN connections. The connection worked, it was just very slow.
So, you have an internal DHCP server handing out IP to the GVC users?
ASKER
No, DCHP was not enabled anywhere. Everything is static (only servers are behind the firewall).
So, you have assigned your GVC a static IP?

1. When the desktop is connected directly to the 2824 switch, a 60 MB file is copied instantly.
2. Through VPN, the same file takes over an hour.
Keep in mind that, even though the transfer is taking place over a VPN connection, all connections are local, gigabit connections (no internet involved). Also, this is a Windows file copy operation, not FTP, HTTP, etc.
