How to configure remote access to multiple subnets behind a SonicWALL NSA 2400
- by Kyle Noland
I have a client that uses a SonicWALL NSA 2400 as their firewall. I need to setup a second LAN subnet for a handful of PC. Management has decided that there should be a second subnet even though intend to allow access across the two subnets - I know...
I'm having trouble getting communication across the 2 subnets. I can ping each gateway, but I cannot ping or seem to route traffic fron subnet A to subnet B.
Here is my current setup:
X0 Interface: LAN zone with IP addres 192.168.1.1
X1 Interface: WAN zone with WAN IP address
X2 Interface: LAN zone with IP address 192.168.75.1
I have configured ARP and routes for the secondar subnet (X2) according to this SonicWALL KB article: http://www.sonicwall.com/downloads/supporting_multiple_firewalled_subnets_on_sonicos_enhanced.pdf using "Example 1".
At this point I don't minding if I have to throw the SonicWALL GVC software VPN client into the mix to make it work. It feel like I have an Access Rule issue, but for testing I made LAN LAN, WAN LAN and VPN LAN rules wide open with the same results.
