I Have a weird problem.
I’ve configured our HQ Fortigate 600C v5.2.2 to do an IPSEC tunneling with PEPWAVE MAX BR1 located in one of our office branches.
my goal is to have IPSEC redundancy over 3G when the DSL is out.
when the 3G is connected, the IPSEC status on both ends indicates ESTABLISHED but no packets are passing (none showing in the fortigate logs).
i was sure i was having configuration issues with the fortigate until i connected an ethernet cable to the WAN Port of the BR1, suddenly all is well, packets are passing between the two networks.
i unplugged the ethernet, IPSEC status remains ESTABLISHED but no packets are traveling over the tunnel anymore, connecting the Ethernet, traffic resumes.
There is internet connectivity when the 3G and when the Ethernet is connected. both working fine, only the IPSEC is giving me problems.
BR1 Firmware: 6.1.2
Any suggestions? ?
