Dear Experts,
I have Configured Cisco ASA 5550 as VPN Server in Head Office.
I configured Cisco ASA5505 hardware client in Branch.
Tunnel is up & I can access my branch local machine from H.O LAN. But I am unable to ping / access Local Network in Head Office from Branch machine.
It is just one sided communication right now.
Need help.
Thanks

Is your ezvpn client/PAT mode or NEM (Network Extension Mode)?
If it's NEM, then you would need to add the following on your inside_nat0_outbound ACL:
access-list inside_nat0_outbound permit ip 10.10.10.0 255.255.255.0
Also, please add the following command on ASA5550:
management-access inside
And from the remote host, see if you can ping 10.10.10.1.

Have you configured NAT exemption on the HQ ASA?
Can you share the HQ ASA config to see if there is anything missing from the config?

Dear Jennifer,
I have installed ASA 5505 as VPN Client in Branch it’s connected with Our H.O. Both LANs are communicating each other smoothly.
We have some Laptop users which they are connected with our H.O through VPN Client application.
Question:
Can laptop users communicate with Branch LAN?
Thanks,
I.A
