Network Backup


Good Morning/Afternoon all,

I am presently setting up a backup for a e-mail server running Postfix and all that good stuff. The email server exists on a 192.168.10.1 network and my backup in 192.168.11.1. I have asked my SmoothWall to forward all Samba ports from 192.168.10.1 to 192.168.11.1. When I issue to command to mount the shared directory on the Windows server to my email server so I can commence the backup I get "connection refused". Ports that are forwarded are 445, 137-139. Any help would be great.

Some clarification needs to take place first. There are two networks here: 192.168.10.0 and 192.168.11.0. These networks are being serviced by a SmoothWall firewall that's making routes between the networks.
As for the actual hosts on the networks, the email server has an IP address 192.168.10.1 and your backup, 192.168.11.1. I'm not too sure about how you are "forwarding" ports but drawing a simple picture would help with that process. What you described in "forwarding" sounds like you are making the email server only talk to one machine rendering it useless.
Please try to be as detailed as possible in your reply because I doubt I completely understood you here. Thank you.

Rather I have allowed ports 137-139 and port 443 for samba connections to be allowed. The picture is best explained as 192.168.254:441 as the firewall, 192.168.10.x as one network which contains my e-mail server, 192.168.11.x network which contains workstations and other services.

I'm still not understanding your configuration here. Your servers can't have a "network" assigned to them. The network refers to a range of addresses in a network. So if you have a network of 192.168.10.0 then your email server has an address on that network like 192.168.10.1 through 254.

As for your discription of the firewall (router), I'm afraid you just complicated me a bit. An internal IP and external IP address of which both have to have 4 octets assigned. So 192.168.254:441 is an invalid description of your firewall's internal IP.

This is what you are describing to me in the virtual world:

Code:
[INTERNET]--[SONICWALL ROUTER 192.168.10.0]---[EMAIL SERV (192.168.10.1)]
          |           Same Router
          |-[SONICWALL ROUTER 192.168.11.0]---[EMAIL SERV BACKUP (192.168.11.1)]
This is how you have set it up right? Sorry if we are taking steps backward. I have to understand what your setup is before I can formulate a plan.

Sorry about the last post was unclear.

- The router/firewall resides at 192.168.10.254
- There are two subnets. 192.168.10x and 192.168.11x

SmoothWall for Samba Declares:

Protocol:TCP
External IP: 192.168.11.1
Source IP: DEFAULT
Source Port: 137
Destination IP: 192.168.10.1
Destination Port: 137
Enabled: Checked.

What I am wishing SmoothWall to do is allow traffic originating from 192.168.11.1 using samba, connect to 192.168.10.1.

Thanks Again.
