Protecting FTP and SMTP

Postby Stewart » Nov 14 03 1:08 am

Hi. I’ve just downloaded the new Kapersky AntiVirus for WinGate and it seems to be protecting my WWW traffic quite well (although it doesn’t seem to catch the test virus inside a zip).

On the Wingate server am running a number of other services including an SMTP server and an FTP server. Is there anyway I can protect traffic on these services with Kapersky AntiVirus and Wingate?

I believe only the integrated WinGate services are protected by KAV for WinGate.

I suspected that might be the case but wondered if I could perhaps reroute traffic to the FTP server through WinGate first?

If they were on a different server I would think you could do that for both.

Might be doable with some fancy port mappings as is. Change the ports for the non-WinGate services to something other that their normal 25 & 21. Might just work!

Not sure if the other programs will like that but I'll give it a go. Thanks for your help.

Let us know if you're successful. It will be a good reference for others.

Partial success!

Creating an FTP proxy service and redirecting it to another port on the server (after reconfiguring the FTP server to talk on that port) does work but can’t handle PASV mode, which unfortunately, I need to support.

Doing the same for the local POP service (I figure I’ll leave the SMTP well alone and catch any viruses on the way to and from the client) seems to work OK. It won’t allow the server to deliver infected mails to the clients, however it does seem to allow infect mails to be sent from the clients to the server and out into the aether.

As long as WinGate is the default gateway for the client machines, and the have to use WinGate to get to the machine hosting the other services, then WinGate will redirect POP and FTP (and smtp in a way) up to the services for testing.
However its hard if you are on the same sub net as the server. In that Case I would assign an additional IP in a different subnet to that server machine, and one on the same subnet to WinGate, and point the clients to the servers new IP, forcing Wingate to route for it.
