Hi, I have a pfsense behind a Telekom Speedport W921v which connects a IPSec VPN to a Palo Alto device which has been working fine for months.
However last night traffic stopped for no apparent reason. The pfsense WAN address is a 192.168.2.0/24 provided by DHCP om the Speedport and there is no forwarding rules in place on the Speedport. The confusing part is the tunnel is showing as active on the Palo Alto and when rebooting the Speedport I see it connecting again, but no traffic is reaching the other end of the tunnel i.e. pings, telnet or rdp I'm currently wondering if the Speedport has had some sort of update that requires us to forward UDP 500 / 4500 etc now but like I say it has been working fine for months until last night. Does any one have any thoughts on it? Unfortunately switching the Speedport to modem mode isn't an option currently. Many thanks Peter.
