Hiya, You would need to allow traffic between the to boxes on ports 111 (tcp and udp) and 2049 (tcp and udp). You would use something like the following. On the nfs source server: iptables -A INPUT -p tcp --source [ip address of host mounting resource] --dport 111 -j ACCEPT iptables -A INPUT -p udp --source [ip address of host mounting resource] --dport 111 -j ACCEPT iptables -A INPUT -p tcp --source [ip address of host mounting resource] --dport 2049 -j ACCEPT iptables -A INPUT -p udp --source [ip address of host mounting resource] --dport 2049 -j ACCEPT then you would need to dump the rules to the script file that gets loaded at boot time... iptables-save > /etc/sysconfig/iptables You may want to actually check what rules currently exist and what the default policy of the INPUT chain is. You may have to insert the rules at a specified position rather then just appending to the chain. i.e. iptables -I INPUT 8 ... to insert a rule at position 8. Try that and see if it helps. regards -art >>> andy.allen@xxxxxxxxxx 13/01/07 11:05 AM >>> Managed to mount nfs file system on RedHat9 by using command '/etc/init.d/iptables stop' on both machines. It seems a bit tedious to have to do this every time - is there a way of doing it at boot-up without having to 'stop' iptables on the command line?
