Does anyone know how to allow outbound ICMP traffic on a Netgear DG834G
router without simply allowing everything outbound?

Basically, I've tightened security on the DG834G to only allow outbound
those services I want users to run (eg. HTTP, DNS, etc.) through a series of
firewall rules. This works absolutely fine. However, I also wanted to allow
outbound pings, tracert, etc. and I cannot see how to allow outbound ICMP
traffic. If I try to define a new Service I only get the options of service
type TCP or UDP.

Any ideas?

Thanks, David

You'll have to enable the telnet service on the router and enable it that way. It is not available through the web admin which is a pain!

Note any changes you make to the router via telnet are lost when the router is reboot.

To enable telnet on the router, go to http://x.x.x.x/setup.cgi?todo=debug where x.x.x.x is your router's ip

Now start a telnet session to the router (start->run->telnet x.x.x.x)

Type the following in the telnet program

iptables -I OUT_FILTER 1 -p icmp -j ACCEPT

you should now be able to ping
