Hi, I am configuring Cisco 2611 router for Internet connection with VWIC 2MFT G703 interface card. router has 2 fastethernet ports and 2 E1 ports ( VWIC 2MFT g703 card). Service Provider has provided the G703 unframed signal and encapsulation is ppp. I configured E0/0 channel-group 0 is unframed and clock source is line and configured WAN IP to s0/1:0 and LAN IP (public ip) to FastEthernet 0/0. I am able to ping gateway IP. But not able to ping other public IPs. Please suggest me Building configuration...
