***Official Disclaimer*** Neither I nor Alltel/Windstream/Your ISP/Anyone else will be held accountable for what you or anyone else does inside your router or on your computer or any software you download and/or install. If you change/remove/corrupt something up on your computer or router or equipment and someone has to fix it or replace it for you and charge you money/services/beer for fixing it then it's your responsibility not mine nor is it Alltel/Windstream's or your ISP's or anyone else's. I give you the information that I have learned/found/acquired. What you do with it is up to you. Do not email me with questions or complaints about why your router/computer/equipment/etc. doesn't work. I cannot guarantee that this config or these settings or information on this site will work for everyone. I can't test all solutions possible because I don't know them all and there are not enough hours in the day/week/month/year for me to test every combination possible. I have tested/used these configurations/software and they work for me. I am just letting my findings be open to help others in times of need at no cost. If you do not understand these instructions/configurations/software or are afraid that you will mess up the computer/router/equipment/software then you will want to contact a computer/network technician to help fix/configure/build what you need done.

I've provided here two Cisco 67x series configs for PPPoA encapsulation, one for dynamic IP's and one for static IP's. Remember, you have to have static IP's assigned to you from your ISP to have the static IP config to work, most of the time this will cost you extra so if you are not sure if you have static IP's then contact your ISP.

Static IP Setup Printer friendly version set nvram erase This command clears the current config. write This command writes to NVRAM. set password exec EXEC PASSWORD This will be the password for exec level access to your router. set password enable ENABLE PASSWORD This will be the password for enable level access to your router. set rip disable Disables RIP config. set tftp disable Disables TFTP access to the router. set snmp disable Disables snmp for router. set nat disable Disables nat routing for router. set web disable This disables the web access interface for the router. set web port 61000 this sets the router to use port 61000 for it's web interface. This is a guard against the Code Red / Nimda virii sweeping the internet. set web remote 192.168.50.50 This sets what IP address the router will allow web access from. Yet another guard agains the Code Red / Nimda virii sweeping the internet. set dhcp server disable Turns of the DHCP server in the router. set ppp wan0-0 ipcp 0.0.0.0 Set the IP address for the DSL WAN interface This is your router's connection to your ISP. Leave this set to 0.0.0.0 to let the router obtain this automatically. set ppp wan0-0 dns 0.0.0.0 This will set the DNS server that your router will use. Leave this set to 0.0.0.0 to let the router obtain this automatically. set ppp wan0-0 login YOUR USERID This is the userid assigned to you by your ISP. This setting is case sensative. set ppp wan0-0 password YOUR PASSWORD This is the password assigned to you by your ISP. This setting is case sensative. set ppp restart enable This setting will allow the router to reset it's PPP connection automatically should it drop. set int eth0 address XXX.XXX.XXX.XXX This will be your router's IP address. The X's will denote your router's IP address. set int eth0 mask 255.255.255.XXX This will be your router's subnet mask. In almost all cases this will be a class C subnet mask such as 255.255.255.248 (If you have static IP +5) or 255.255.255.252 (If you have static IP +1 set prompt PROMPT This will allow you to set your CBOS prompt. set int eth0 speed auto This will allow your router to auto-negotiate it's port speed for 10Mbit/100Mbit and half-duplex/full-duplex, leave this set to auto otherwise the router will not have the correct port speed. write This writes the current config to NVRAM. reboot This reboots the router.

Dynamic IP Setup Printer friendly version set nvram erase This command clears the current config. write This command writes to NVRAM. set password exec EXEC PASSWORD This will be the password for exec level access to your router. set password enable ENABLE PASSWORD This will be the password for enable level access to your router. set rip disable Disables RIP config. set tftp disable Disables TFTP access to the router. set snmp disable Disables snmp for router. set nat enable Enables nat routing for router. set web disable This disables the web access interface for the router. set web port 61000 this sets the router to use port 61000 for it's web interface. This is a guard against the Code Red / Nimda virii sweeping the internet. set web remote 192.168.50.50 This sets what IP address the router will allow web access from. Yet another guard agains the Code Red / Nimda virii sweeping the internet. set dhcp server enabled Enables the DHCP server on the router. set dhcp server pool 0 size 128 Sets the DHCP server to use upto 128 ip addresses. set dhcp server pool 0 ip 192.168.200.2 This will be the first IP address in the DHCP pool that the DHCP server will assign to your computers. set dhcp server pool 0 gateway 192.168.200.1 This will be the gateway address that the DHCP server will assign to your computers. set dhcp server pool 0 mask 255.255.255.0 This will be the subnet mask that the DHCP server will assign to your computers. set dhcp server pool 0 dns 166.102.165.11 This is the primary DNS server that the DHCP server will assign to your computers. In this example I am using Alltel's primary DNS server. set dhcp server pool 0 sdns 166.102.165.13 This is the secondary DNS server that the DHCP server will assign to your computers. In this example I am using Alltel's secondary DNS server. set ppp wan0-0 ipcp 0.0.0.0 Set the IP address for the DSL WAN interface This is your router's connection to your ISP. Leave this set to 0.0.0.0 to let the router obtain this automatically. set ppp wan0-0 dns 0.0.0.0 This will set the DNS server that your router will use. Leave this set to 0.0.0.0 to let the router obtain this automatically. set ppp wan0-0 login YOUR USERID This is the userid assigned to you by your ISP. This setting is case sensative. set ppp wan0-0 password YOUR PASSWORD This is the password assigned to you by your ISP. This setting is case sensative. set ppp restart enable This setting will allow the router to reset it's PPP connection automatically should it drop. set int eth0 address 192.168.200.1 This sets your router's ethernet interface IP address. set int eth0 mask 255.255.255.0 This sets your router's ethernet interface subnet mask. set prompt PROMPT This will allow you to set your CBOS prompt. set int eth0 speed auto This will allow your router to auto-negotiate it's port speed for 10Mbit/100Mbit and half-duplex/full-duplex, leave this set to auto otherwise the router will not have the correct port speed. write This writes the current config to NVRAM. reboot This reboots the router.
