Pfsense VPN: IPSEC - Ping problem
I have configured a normal ipsec vpn which is sorta "working".
SiteA: WAN: 172.16.241.185 /23
LAN network: 192.168.10.0 /24
SiteB: WAN: 172.16.241.190 / 23
LAN network: 10.0.10.0 / 24
Now the vpn is setup and it seems to be running. The problem I have now is that when a client on siteA pings a client on siteB
the pings doesn't reach the client. But if a few seconds later the client on siteB pings the client on siteA, all of a sudden client on site A is able to ping the client on siteB.
It seems the tunnel can only be opened when the 2 clients are pinging. And it doesn't stay open for very long.
I hope someone can help me with this issue thanks!
Btw I'm using pfsense 2.2.1 amd64
What does Status>IPsec look like? What do your firewall rules on the IPsec tab look like?
You could set the phase 2 configuration in site B to ping an internal IP in site A.
Otherwise it looks like you have a firewall or NAT issue, or accidentally checked "Responder Only".
