Hi,


I need some help. I have 2 offices (1 in viet and 1 in singapore). These 2 offices already have site to site vpn setup. However, when i try to add in the VOIP network (172.28.200.0/24) into the site to site vpn. I am still unable to reach my call manager from viet office.



See below picture for the site to site VPN network. Same setting for viet asa except the local n/w would be 172.29.52.0/22.

Hi,


Would really need to see configurations from the ASA or some other output to determine what the problem is


The most common problems would be that the Crypto ACL are compatible with eachother on the sites. One problem could also be that you are lacking the NAT0 / NAT Exempt configuration for this network on both sites.
