DNS Proxy cannot reach the VPN Site

JaZZ
Hi Folks,

I have a site to site vpn tunnel established, IP traffic works very well between my two sites. But i need  to query the internal dns-servers with the DNS-proxy of the remote site.

From the maschine(firewall) on the remote site i can't reach the internal DNS servers. Which rule should i add? MASQ or SNAT, etc ? Is there a way to use DNS-Proxy and trnsparent HTTP- Proxy?

Thanks in advance

    JaZZ,
    since the DNS Proxy uses always the IP address, the default gateway is set on for outgoing traffic, which is not inside the tunnel definition, you need a SNAT like:
    From: Internal
    To: Remote Subnet
    Service: DNS
    Chnage Source to: Internal Address

    That should work!
    Cheers,
