Routing

Hi all, my company just bought a new SG310 Hardware, I have configured the LAN and WAN on it, but I dont know how to configure my lease line to connect our other branch, which also have Sophos SG310, so that both can communicate, although there is an existing linux gateway that I want to replace with sophos firewall, can someone explain how to configure lease line on SOPHOS SG310 firewall. The ISP link is already available.

I am not quite sure what you mean by Lease line? 

Thanks Toni, I mean is that I have Company A and B on different locations. I have SOPHOS on both locations as the gateway, Irrespective of the geographical location I want them talk to each other, I want to be able to remote to any host on other location. This is what i mean by lease line or may be dedicated point to point line.

There are different approaches to connect Sites.

One would be the classic Site to Site VPN via IPsec.

More rare case is to use the Sophos Own RED protocol: https://community.sophos.com/kb/en-us/125101

IPsec will have more throughput.

RED gives you a "Layer 2" cable between both. 

Thanks, but what if I have a dedicated LAN tunnel from my Internet Service Provider, how am I going to configure the 2 SOPHOS, instead of using IPSec that route through the Internet? Or which on is better?

Thanks, but If I already have additional dedicated LAN port enabled by my Internet service provider, how can i configure my SOPHOS through my ISP dedicated line, instead of the IPSec that connect through the Internet, or which one is better?

I have the same question, did you ever get it to work?

Can you share a network diagram?

Thanks
