you have encrypted and decrypted packets.

and you negotiated NAT-T

so your vpn is working.

if you want continue - give more details.

Here it looks everything fine, but the thing is.

My LAN network is 172.0.0.0 series and client will get 10.10.10.0 series. Client is getting the IP address but unable to access the 172.0.0.0 series.

If required more inputs then i will provide.

show the configuration :)
