If i understand you correctly, u're successfully established tunnel between one 5505 acting as ezvpn-server and other 5505 acting as ezvpn-client in netwrok-extension mode.

Everything fine with tunnel establishment, but you can't ping outside ip of your client device. You mean public outside ip?

Isn't that device behind nat? What IP you're trying to ping? It's certainly reachable from server device, otherwise the tunnel woudn't establish. Only thing - maybe it's behind nat.

About pinging inside interface: probably you can use command management-access inside. But i'm not sure it'll work on client device, though it should.

VPN is established but 2 asa devices cant ping each other, and pc on client side cant ping pc on server side and vice versa. I added management-access inside on server and client side but then only client can ping router gateway of server not the inside interface
