Hi.
I created IPSec tunnel between two offices.
One side (SITE1): 192.168.0.0/24 and local gateway is 192.168.0.254 (MikroTik)
Other side (SITE2): 192.168.1.0/24 and local gateway is 192.168.1.254 (MikroTik)

Servers in the SITE1. DNS server in the SITE1. DNS1 = 192.168.0.250
Clients in the SITE2.

When I try to ping DNS1 from client (from SITE2) it's ok. And if I try to ping 192.168.0.250 interface=bridge-local from MikroTik from SITE2 it's ok.
But if I try to ping DNS-server from SITE2's mikrotik (without interface=bridge-local) I got timeout. That's means that Mikrotik from SITE2 can't resolve DNS-names with help of DNS1.

So... What is the best practice? How to forward all DNS-queries from SITE2's mikrotik to the DNS1 (in the SITE1)... And ntp-queries too.
