SonicWall TZ190 - 2 District Offices - 1 Main Office
Posted on 2010-09-09
I am installing a TZ190 firewall and am having troubles.
We have one main office which uses 10.0.0.0
We have a District office using 192.168.1.0
and another district office using 192.168.2.0
Each site has its own external IP address
All sites are connected together with a CISCO router and VLANS, so that all the sites meet at the router.
The internet is put through the firewall and then both plug into the switches.
Both the router and firewall plug into the internet box from Ontera so that the router has external IP of .194 the firewall has .195
the district sites have .196 and .197
So, right now I have things working a little bit, the NAT for out webmail server, the internet for the main office, but...
the district offices do not have internet, I think it has to do with IP Spoofing, since the IP addresses are a different network (192.168.0.0) the firewall thinks they are sppoofed because the main office is (10.0.0.0)
This is major confusing but if anyone can give me some hints for the Sonicwall TZ190 in this situation. Even what I use, ie, do I use NAT or Routing or address objects.
I thought I was a pretty smart IT guy untill I tried to set this firewall up...
