I'm trying to set up a network with the following design and wanted to see if there would be any problems with remote users being able to make a VPN to the Cisco router configured as a VPN endpoint. My design is attached as a JPG file and VPN clients would use a pool of addresses configured on the Cisco 1720 (configured as a VPN endpoint) and would be something like 10.10.10.150 - 10.10.10.200. These VPN users need to access the servers on the 10.10.10.0 subnet
My question/concern is will having the Sonicwall firewall performing NAT cause a problem with VPN clients connecting to the Cisco 1720 router (configured as a VPN endpoint)?
I was going to configure a static NAT on the Sonicwall firewall so that VPN clients would connect to a 200.200.200.x address and the Sonicwall firewall would then NAT this to a 192.168.0.x address on the Cisco router. Will this NAT affect the ISAKMP/IPSec traffic and not successfully establish the VPN
Do you have a sample configuration (router and/or VPN) that I could reference for this type of setup?
Thanks in advance
