Dear all ,
We have a new internet connection from DSL cisco router 800 Series (877).
You has been delivered it to us with Cisco Router 800 series (Ver 877), when we connect it to the PC directly it’ll work fine with the static IP.
We configured the OSPF between the Switch and the Router. and we can reach to the DSL router IP from our LAN any where.
but we can't exit from the router to the internet.
Please i need your advice
