IPsec VPN change from ISP and it does not work correctly
I have the problem between a VPN tunnel between two FortiGate a 500E and a 60E.
The VPN tunnel existed between the two computers and it was functional, but in the FW FG60E the ISP provider was changed, the new ISP was placed in the WAN2 of the equipment, the old tunnel used WAN1 (the link was already deleted).
After the link provider change, the IPsec VPN tunnel is established, but the communication inside the tunnel no longer works.
The data of the 500E firewall comes out, the 60E firewall receives it, I see the answer coming out of the 60E, but the 500E firewall no longer receives any packet.
Please help me to solve this issue, thanks!
