What is the CLI command to restart the network connection without having to do a total re-boot into Blag?
/sbin/service network restart
I've noticed with some broadband connections the cable/dsl modem needs to be rebooted as the ISP tracks MAC addresses for DHCP.
Also, you can share your connection with NAT, if you have a hub or dual ethernet in one of the cards. Here's my "nat-on" script:
# insert masquerade module
# flush old rules
iptables -t nat -F
iptables -t mangle -F
# turn on NAT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
# forward IPs
echo 1 > /proc/sys/net/ipv4/ip_forward
Where eth0 is the ethernet connection to the internet.
