Hello Everyone

I have a configuration problem and I cannot identify which is the 
problem I may give too much information but here it goes...

The problem I have is on the JNOS side cannot connect to the Internet 
.  I can ping up to the router but not outside the router to the Internet.

On the Linux Side I can ping the Internet www.yahoo.com ...but not on JNOS.

My host for my Internet is Comcast

I also have forwarding on in linux.

Jnos ifconfig shows ...

Here is my Autoexec.nos setup

DNS server info
domain addserver
domain addserver 68.57.xxx.xxx  (my Comcast ip)

Ethernet setup

attach tun tun0 1500 0
ifconfig tun0 ipaddress
ifconfig tun0 netmask
ifconfig tun0 mtu 1500
pause 2
shell ifconfig tun0 pointopoint mtu 1500 up

also down the line
route add tun0
route add default tun0
route add 44/8 vhf

I hope I provided enough It seems like JNOS and Linux are not 
agreeing on the ports or jnos does not have permission but I am not 
sure how to set it if this is the problem.

I would like some help with this as it is about the last thing I have 
on the ether net side to do .

Thanks to everyone
