We are trying to setup and evaluate web based backup for client sites.
In doing our inhouse testing we have configured our server with the appropriate software and poked a hole in the hardware firewall at port 308 to allows traffic from selected IPs (so far so good....) Our default firewall sits at 192.168.10.1 on the local / internal subnet.
Next we configured a network workstation with the client software and told it to go outbound via gateway 192.168.10.5 (SME 5.5 server) as a backdoor firewall / proxy server. This server is running in gateway / server mode. The backup client software asks if you are behind a firewall or not and asks SOCKS type and port # (we selected SOCKS 5 / port 3128) and the connection test failed. Next we selected SOCKS 4 and port 3128 with the same result.
The only thing that I could figure here is that the SME server (squid proxy) is not allowing the requested connection to port 308 on the backup server. Next I checked allowable ports in the /etc/squid.conf and added port 308 as a defined & allowed port.... same result.
Does anyone have any insights here - I am at a loss as to where to go next (99% of our security implementations tend to use hardware firewalling but I would like to be able to use this service on sites where we have SME servers).
Thanks,
