Add in VOIP network in Site to Site VPN (ASA 5510)

[hokokshun]

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.
                  

THanks in advance!

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.
