Hi,
I came across your post as I am having some difficulty tethering my Novatel 5510L to my router using openwrt. Theoretically this should be little different than tethering it to any other linux system.
I believe that I only need some help with respect to the iprouting described at the end of the post.
iptables -t nat -A POSTROUTING -s 172.16.42.0/24 -o eth1 -j MASQUERADE
iptables -A FORWARD -s 172.16.42.0/24 -o eth1 -j ACCEPT
iptables -A FORWARD -d 172.16.42.0/24 -m state --state ESTABLISHED,RELATED -i eth1 -j ACCEPT
I am not really that network savvy (61 year old hardware engineer) and would like some explanation regarding the ip addresses shown above. I expect that they would be different for my system but I am not at all sure of how to determine them. Yes, I an able to log into the 5510L (when attached to my fedora system) and see the advanced tab and see the DHCP range etc. I expect that the last two lines in the above relate to ip forwarding.
Thank You
Tom
