Sonicwall + VLANS to correct network IP scheme

Posted on 2009-05-12

Last Modified: 2012-06-27
Hello, my company has acquired another company and seeing we run Sonicwall's we have installed a 2040 std in the new location. Unfortunately the company we acquired uses 192.155.87.0 as their private or inside addresses, we have established a VLAN and communications are working OK.
Now we would like to transition their inside addresses which may have some hard coded dependencies on their incorrect address scheme. I would like to keep our network 10.n.0.0
and would like to have them be either the old (bad address), or our standard address scheme as we test and transition. Suspect this could be done with sonicwall definitions and VLAN we use procurve managed switches. Can someone point me in the best direction to accomplish this.. The 192 network will be decommissioned once testing of old and new apps is completed.
Thanks in advance for your help.

I think you should be able to do this if you check into NATing

Presuming you are using Enchanced OS on both ends, this should be simple.

Just create an Address Object which includes both Old and New private ranges for the target site.

Now when setting up the VPN tunnel definition for that site, use the created Address Object when defining the Destination Networks.

The system should now set up a tunnel with routing for BOTH those destination ranges being "via" that tunnel.

Went to Procurve and it was determined that we had invalid tagging between switches and we had to take the sonicwall out of the vlan config.. Thanks for the effort..
