Cisco 678 and SBC Yahoo DSL... Help please!

[SeRi@lDiE]

OK I am new here so here we go....
I just got a Cisco 678.. I am tring to set my Modem to work with SBC Yahoo DSL the only tricky part is that I have dynamic IP...
Also I dont want to use the NAT and DHCP function of the router part because I have a ZyWall 10 Hardware Firewall all I want is preatty much to act as modem if its posible.
Thanks a lot for all the help!

[SeRi@lDiE]

Any body out there have any idea on how can I do that?

[SeRi@lDiE]

I saw the following config in one of the post here in the forum....
set ppp restart enabled
set ppp wan0-0 ipcp 0.0.0.0
set ppp wan0-0 dns 0.0.0.0
set ppp wan0-0 login ( Supplied by your ISP )
set ppp wan0-0 password ( Supplied by your ISP )
set nat enable
set nat timeout udp 3600 ( for online gaming )
set nat timeout icmp 3600 ( for online gaming )
set dhcp server enable
set int wan0-0 disable
write
set wan0-0 vpi 0
set int wan0-0 vci 32
set int wan0-0 enable
set ppp wan0-0 subnet 0.0.0.0
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

You are finished! Close Hyper Terminal and you should be able to connect to the Internet


But I see that they have DHCP and NAT enable.... Is these the only way you can use these modem?
Thanks in advace for all the help and input!

Welcome to XPC SeRi.

I'm not familar with SBC required settings but I'm currently searching for their setup. They should have sent you connectivity info which should get you online. Once you are online then you should be able to go in and "tweak" it to how you want as long as the required settings dont change (such as the NAT and DHCP.

[Mntsnow]

btw have you checked out the SBC-Yahoo DSL forums at dslreports? http://www.dslreports.com/forum/ilec,am

[SeRi@lDiE]

Thanks for your reply Mntsnow!
I know SBC requires DMT so as far as I know I am ok from there...
My current setup is PPPoE I use my Hardware Firewall to loging... The firewall has the username and pass... I am tring to connect the modem to the WAN port in the Hardware Firewall..... I get a link but no go.....
What is it that I need to know from SBC?
By the way I all ready ask for help in dslreports no go though....
So I PM one of the techs...
Thanks a lot!

[Mntsnow]

How do you currently have your setup?

Start from the Internet and work your way back to your desktop

such as

Internet
dslmodem
firewall
hub
desktop

[SeRi@lDiE]

OK here is my setup as fallow....
SBC Yahoo ADSL 1.5/256 ----> Speed Stream 5360 ----> ZyWall 10 (PPPoE to login to SBC... and also acting as my DHCP Server) ----> Netgear RO318 (Acting as simple switch... DHCP and NAT Disabled) -----> to 6 computers using DHCP provided by the ZyWall 10.


So what I am tring to acomplish is...
Take out the Speed Stream out of the picture and replace it with my Cisco 678..
I am in to the point that it dont matter no more if I have to use the DHCP and the NAT out of the Cisco 678 as long it I can connected it to the WAN Port of my ZyWall 10 and the ZyWall 10 to my RO318 to all my computers.
:(I just would really like to stick with My ZyWall 10 as my DHCP server because I know how to work it preaty well!
Thanks a lot Mntsnow you have been a grate help!
Every where I go no body even replys to me... I know these cant be to hard for those who know cisco preaty well! :)
Thanks again!

[SeRi@lDiE]

ok here is the info given by SBC....
VP/VC 0/35

DNS
pri-- 151.164.11.201
sec-- 151.164.1.8
pppoe

[Mntsnow]

should be pretty much a straightforward deal at that point following the Bridging instructions just substituting your SBC values in the guide since you use the firewall for your PPPoE

http://www.xtremepccentral.com/forums/showthread.php?threadid=3703.

[SeRi@lDiE]

So my config should be as fallow....

set ppp restart enabled
set ppp wan0-0 ipcp 0.0.0.0
set ppp wan0-0 dns 0.0.0.0
set ppp wan0-0 login ( Supplied by your ISP )
set ppp wan0-0 password ( Supplied by your ISP )
set nat disable
set dhcp server disableset int wan0-0 disable
write
set wan0-0 vpi 0
set int wan0-0 vci 35
set int wan0-0 enable
set ppp wan0-0 subnet 0.0.0.0
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

And what should I set up my ZyWall 10 to be?
Because in the manual it dont tell you how to get the modem to work with other routers.
Thanks.

[Mntsnow]

Sounds like you need to setup Bridging since you need PPPoE and you use your firewall to do that Lastly...What firmware version are you running on your 678? and it is DMT firmware correct?

set bridging rfc1483 enable
write
reboot
enable
set client dhcp enable or disable if your going to do dhcp from firewall
write
set int wan0-0 disable
write
set int wan0-0 vpi 0
set int wan0-0 vci 35
set int wan0-0 enable
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

[SeRi@lDiE]

Firmware is v2.4.3 and yes is DMT :)

[Mntsnow]

You might want to update to the latest which is 2.4.6 while your going thru all of this
