[plshlpme]

thats the only thing i can think of is that maybe the dns or ip that your assigning statically is no longer valid...

as far as your isp is concerned since your overloading on your wan interface your whole lan should appear to be a single host.

is your internet service advertised as a static ip address?

ip address 70.x.x.x 255.255.255.252 \\static public address

did they assign that /30 to you or did you get it once via dhcp?

Hi Everyone!

Yes, It is static IP from TWCNC. Now I config like this -
ip default-gateway 70.x.x.x
ip nat pool VIM 70.x.x.x 70.x.x.x prefix-length 30
ip nat inside source list 1 pool VIM overload
ip classless
ip route 0.0.0.0 0.0.0.0 70.x.x.x \\point to ISP Def-GW

Now it is working. Thanks alot for your cooperation.

Now I going for VPN setup.
