I'd appreciate if you could help.
Currently, the IPSec L2L VPN is perfectly working fine using Cisco ASA 5510 (at HQ) and ASA 5505 (at partner place). I can ping from HQ to any internal IP address of partner site and vice versa.
How to restrict only one-way direction by only HQ can access the network of partner site, for example, RDP to a server which located at partner site. In partner network, they cannot RDP to any machine/server in HQ.
Please note that I have configured L2L through ASDM Wizard. It was a default settings. HQ network segment is 192.168.20.0/24 and Partner network is 192.168.1.0/24.
Thanks in advanced.
