VPN/Routing Question

gr33ny

Hello

 

I have an SG210 running 9.409-9.  We need to establish a VPN with a partner but one of their existing clients is using the same subnet as our local subnet.

 

 

I've seen the instructions in this KB article explaining how to set up a VPN when both VPN devices use the same local subnet by creating a fake subnet and a 1:1 NAT rule at either end.

 

Is it necessary for me to set up a fake subnet if one of our partners existing VPNs uses the same local subnet as us?  If I do need to setup a fake subnet should I then be just setting up a NAT rule from side?

 

Many thanks

    Thanks for confirming - just in case anyone else comes across this post my NAT rule looks like:

    For Traffic From: My Local subnet

    Using Service: Any

    Going to: My partners local subnet

    1:1 NAT Mode: SOURCE

    Map to: The fake subnet I set up
