[nos-bbs] FW: Jnos networking problem

[Mark Phillips]

Here's a cutting from my autoexec.nos. It creates the JNOS side of the tun
interface. Shells out to the OS to create the Linux side of the tun
interface. Issues ARP commands and then finally adds some routes so that
things will flow up and down the tun.

# Set up TUN port ********************************************
attach tun tun0 1500 0
ifconfig tun0 ipaddress 44.64.28.6
ifconfig tun0 netmask 255.255.255.248
ifconfig tun0 mtu 1500
pause 1
shell echo 1 > /proc/sys/net/ipv4/ip_forward  # make sure that we are
forwarding IP on the Linux box - won;t work without this
shell ifconfig tun0 44.64.28.2 netmask 255.255.255.248 pointopoint
44.64.28.6 up  # set up the Linux side of the interface
shell arp -i eth0 -Ds 44.64.28.6 eth0 pub  # publish the ARP so that Layer2
is satisfied
shell route add -host 44.64.28.6 tun0  # add some routes so that Linux
knows where to find us
shell route add -net 44.64.28.8/29 tun0
#
ifconfig encap ipaddress 44.64.28.6

Hope this helps.

Mark
