Problem access internt using DNS in firewall.
Hi all, I have setup my firewall as my DNS server. Lately I have problem browsing internet from my LAN, it seem my DNS server down and cant ping to any host like google or yahoo. But after trying couple of times, I can access that site again. My router and modem is working fine. I still can do nslookup from the server to yahoo or google. It only happen for 1-2 times and sometime we can easily acces the internet. It's like my server cant hold all access to internet, but I only have 50 PC's accessing internet. Anything I should check ? maybe in Firewall or anywhere ? regards, -- Arie Reynaldi Zanahar reymanx at gmail.com http://www.reynaldi.com
Try to ping some external IP address with your cleint first. This will show thether the problem is in the DNS itself or in the firewall setup. If this works, check whether your DNS server can communicate through this firewall, that is TCP and UDP ports 53 should be open.

I think the problem is that my /etc/named.conf contains forwarders {192.127.0.1;}; And my main DNS server (the one with 192.127.0.1) somehow is not working properly. After I restart named service in main server, somehow the connection is up again. The server that i was talking about using 192.127.0.27. regards, -- Arie Reynaldi Zanahar reymanx at gmail.com http://www.reynaldi.com
