17.7 Legacy Series / DNS forwarder cannot resolve site to site hosts

« on: September 05, 2017, 04:56:53 pm »

We have a site to site connection which uses open vpn. The VPN connection working fine, But Cannot resolve hostnames from site B in Site A or vice versa.

But using same DNS forwarder can resolve the host names from AWS VPN Connection(Uses OpenVPN)

DNS Forwarder Configuration.

Enable DNS forwarder   Enable
DHCP registration           Enable
Static DHCP                           Enable
Prefer DHCP                           Enable
DNS Query Forwarding   blank
Listen Port                           blank (53)
Interfaces                           All
Strict binding                           blank

AT Site A
Domain   abc.tld
IP address   192.168.2.1 (this is IP address of Opnsense Box at Main Site B)
Source IP   192.168.1.1 (this is local IP address of opnsense Box at Remote Site A)


AT Site B
Domain   abcd.tld
IP address   192.168.1.1 (this is IP address of Opnsense Box at Main Site A)
Source IP   192.168.2.1 (this is local IP address of opnsense Box at Remote Site B)


Note: Generally, all 192.168.1.x or 192.168.2.x ip addresses are reachable from both sites flawlessly.

Thanks.
