How to setup Sonicwall 2040 for 2 non-contiguous public address ranges
Posted on 2005-05-16
My ISP provided me with 2 address ranges that have a different third octet. We have the sonicwall setup with subnet mask 255.255.0.0 so that it works, but packets are not routed outside to/from locations with the same first two octet addresses. (ie same ISP customers). This has been ok, but now we have a need for accessing one or more of those public addresses.
Our ISP says to simply set the subnet mask for both ranges at 255.255.255.240, and the gateways to their respective hosts, which are different. Unfortunately, I cannot see how to do this on the Sonicwall 2040. Sonicwall had originally advised us to set to 255.255.0.0, and I guess they're the experts, but I just wanted to check if there is a workaround.
Any Sonicwall experts out there? Thanks.
