Hello everyone,
How do I get modbus traffic over IPSec tunnel?
I can ping over the tunnel no problem.
Using modpoll utility I get:
"Protocol configuration: MODBUS/TCP, FC3
Slave configuration...: address = 1, start reference = 1, count = 1
Communication.........: 192.168.71.10, port 502, t/o 1.00 s, poll rate 1000 ms
Data type.............: 16-bit register, output (holding) register table
Can't reach server/slave! Check TCP/IP and firewall settings."
The Digi firewall is disabled.
Any ideas?
