We have 2 sites.
On our site we have a TZ 200 and on the company site there is a NSA 2400.
We have 2 WAN X1 and X2
X1 is on ADSL technology (Static IP from the ISP 194.90.X.X)
X2 is on Cable technology through a IP router (Static IP 10.100.101.100 provided by the IP ISP's router and also static Ip =80.179.X.X)
We have create a VPN tunnel between the TZ 200 and the NSA 2400 (Static IP = 84.96.X.X)
Between the X1 from TZ200 and the NSA 2400 all is working perfect.
When the X1 is down and the X2 is mounting his VPN tunnel with the NSA:
The tunnel is on (green), we can surfing on the web, BUT it's impossible to ping from computers from one site to another or anything else like Exchange or web etc...)
BUT from the TZ 200 it's working????
With find Network traject we have an answer???
If you are needing logs i can add them.
The Lan work on the TZ 200's Site is 192.168.202.x
The Lan work on the NSA 2400's Site is 192.168.83.x
