Hi !
We set the users->HAVP->Internet on the network.
According to well configuration it worked nicely !
but occasionally it issued DNS error.
what should I do ?
Our system configuration is :
HAVP ver.0.89

Thanks in advance
Amir

Do you have local caching DNS server, or do you use your ISP DNS server in resolv.conf? Maybe you get some timeouts.

If you have many users, it's recommended to use Squid with HAVP.

thanks my problem has been solved . :)

I added following line to iptables output chain table:

######################$ dns output $######################
/sbin/iptables -A OUTPUT -p udp -m multiport --dport 53 -j ACCEPT

and added the following line to iptables input chain table:

######################$ dns input $######################
/sbin/iptables -A INPUT -p udp -m multiport --sport 53 -j ACCEPT

and added the following lines to iptables forward chain table:
######################$ dns $######################
/sbin/iptables -A FORWARD -s 192.168.0.0/24 -o WAN1 -p udp -m multiport --dport 53 -j ACCEPT
######################$ reversedns $######################
/sbin/iptables -A FORWARD -d 192.168.0.0/24 -o WAN2 -p udp -m multiport --sport 53 -j ACCEPT
havp doesn't have any problem with DNS... :lol:
