DNS not resolving over VPN
-
Hi All,
I have a IPSEC site to site VPN
Site 1: 192.168.1.0/24
Site 2: 10.10.10.0/24 -> DNS Server 10.10.10.9The PC's in Site 1 cannot resolve DNS via the remote DNS Server…I can ping anything from Site 1 to Site 2 and vice versa via their IP addresses but I can't resolve anything.
Any Ideas?

Any ideas anyone?

Have you setup DNS suffixes in TCP/IP settings on the site 1 systems?
Please can you show your DHCP scope options. -
Tried adding site 1 subnet to the access list ?
Services -> DNS Resolver -> Access Lists

Do you have a windows server handling DHCP?

Since this is basically my same problem.
I setup a site to site VPN.
Site 1 is a remote office.
Site 2 is our DC with our domain controller and DNS servers.
users at site 1 need to reach systems by DNS at site 2.I added a Domain Override to the DNS resolver in the pfsense firewall at site 1 with our domain and the DNS server at site 2 to send the queries to. When I did this the only thing that can be resolved by a DNS is my primary Domain controller. It happens to be a DNS server as well.
I've tried adding the DNS servers at site 2 to the general setup DNS server list as well after the ISP DNS servers.
at Site 2 I have a watchguard firewall.
I looked at this as well https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/access-firewall-over-ipsec.html#ipsec-fwtraffic
but I don't think this is relates since if I set the DNS server on a local machine to the IP of the DNS server at site 2 I can resolve everything at site 2. I'd like to just do this through the pfsense at site 1.I just put my domain DNS server as the primary DNS for the DHCP leases ( Services / DHCP Server / LAN) then google DNS, and then lastly our ISP DNS. Everything works as expected this way.
