Hi there
After hard work and help from few  fellows here i  have a 44 Net connectivity  with  Cisco
1005 router
It has only one Ethernet   and I do the tunneling on the same Ethernet
it is still not perfect but work
I need to add into it the 44 Net Gateways route commands ill do it  in the coming days
Im publishing the  Config file for those that want to build  Gateways from  Cisco  Routers
Some explain
The p route 0.0.0.0 0.0.0.0 Tunnel0 169.228.66.251  line is the tunnel command to route
every  trafic that goes out from the LAN to e internet  (in our case it is every
44.138.x.x  trafic that want  to go out  to the internet  it must be routed to  UCSD
because the ISP  Block  IP which is not belong to them (include 44 Net IP)  to go out to
the outside world  via their routers
The ip route 8.8.8.8 255.255.255.255 Ethernet0 10.0.0.138 is to allow the router to get
DNS (for translating IP to names while I  do traceroute from  inside the router)
The ip route 169.228.66.251 255.255.255.255 Ethernet0 10.0.0.138 is to allow the tunnel
link to be routed  through  the regular Internet connection
Of course that following should be a  route command for every 44 net gateway   there are
few ways to do it
i will start with a script  but im checking  other solutions   as well
If there are Cisco  experts that willing to  improve my config im open to  suggestions
last time i have touch  Cisco stuff was  20 years ago ... some of the commands are new to
me   beside the fact that i  have forgot most what i used to  know
