Hello I have set up a netfilter box as a gateway. The network lookis like this:
subnet ---- eth1 - Netfilter box - eth0 --- modem/router --- FAI
The forwarding/masquerading is working fine, subnet boxes can ping external ip like.
But they can' t resolve domain names, because there isn' t any DNS server in the subnet.
I d like to use DNS Servers of the ISP, or another DNS Server I would set up OUTSIDE the subnet.
The netfilter box has the ISP DNS servers in resolv.conf and its gateway is the router.It resolves domains names without problems.
Is it possible to use netfilter rules to "relay" clients DNS requests ? Sorry but I m new to netfilter.
Thanks in advance. Regards
Axel
