Proxy behind firewall/NAT

Post by mephisto »

Hi there,

I'm having problems to establish what is really going wronjg with a setup where I want to backup to a offsite proxy over the WAN, both sites with firewalls in between. I think ports tcp 2500-5000 are the ones to be directed in and out of each proxy server, but so far I can't reach them in this way to deploy the proxy software. I checked the whole manua, web, google, etc... I can;t find a clear way saying you need this and that ports open on a machine to install and run the proxy server.

Could you guys assist me please? I need to ensure all of this works before taking any move ahead with my client.

Thanks!

Hi.

Your "port" problem seems pretty similar to the one that has been already discussed. Please, check this for solution, especially messages from “cristiano.cumer” regarding his firewall changes.

Hope you'll find it usefull.

Thanks!

Backup server is a Windows 7 machine, destination proxy another Windows 7 machine. Directing only 49152/65535 didn't work. Directing 1024/65535 worked, but this is a hell of a long range of ports. I'm reading some other stuff here but I don't really like the idea of such a long range of ports open. It is a massive attack surface available :/

Well what I ended up doing is, ports 6160 to 6162 (proxy installation, replication ans transport and 49152 to 65535 for RPC.

Worked fine, will run some backup jobs over the WAN later on to test.

Yep, my bad. I should've mentioned it earlier.

Well, I'm having all sort of weird errors when trying to backup up the Vms to a remote location with a proxy. Doesn't matter if it is over a WAN, over a tunnel over WAN, it simply doesn't work.

every time I get different errors, weirdly I've never seen any network related problem with these clients in the past, all tunnels always worked fine :/
