TZ470 IPSEC VPN

wwjdwade

I have TZ470 with an IPSEC VPN to an older SONICWALL and another to a PFSENSE FW. The clients behind both of these networks can ping clients behind the TZ470, but the TZ470 clients can't ping anything behind either of the other two networks. The old SONICWALL and PFSENSE also have a VPN and both sides can ping each other.

Any ideas for me to get the TZ470 clients pinging through the IPSEC VPN?

Thanks - I figured out my issue. I forgot about a couple of VPN to LAN Subnet rules.... Thanks!

Run a packet capture on the TZ470 looking at traffic destined for the VPN tunnel and see what's happening.
