Please verify the my configurations. I have a 1721 router with one fastethernet port and a four port ESW (switch). I wish to connect the fastethernet port to the dsl provider equipment. The DSL provider can only provide dynamic ip. I also will be configuring the 1720 to dish out ip address to the PCS and it will also do NAT overload. Please verify the concept of what i am trying to acomplish.My syntax is all wrong however please verify the concept.
3PCs------1720 ------ DSL Modems1720
ip dhcp pool cisco ip dhcp network 192.168.1.30 - 192.168.1.240 ip dhcp exclude 192.168.1.1
int fastethernet0/0 ip address dhcp {address to be obtained dynamically from provider} ip address nat outside
int vlan 1 ip address 192.168.1.1 255.255.255.0 ip address nat inside
ip route 0.0.0.0 0.0.0.0 fastethernet0/0
ip nat inside source 192.168.1.0 int fa0/0 overload
Will this configuration suffice am i missing anything Where do i configure DNS servers? The clients will connect to the ISP and then launch cisco vpn client to connect to corporate. Will there be an issue with all three vpn clients going? thanks
