Re: WRT54G - Static IP and 4100B modem in bridge mode - Help
NormanS wrote: Can the SS4100B work with a static IP address in any mode other than bridged? I would think not. A static IP address assignment, the old Pacbell assigned type, I think is true static; no DHCP, or PPP log in.
This is evidently true: the old Pacbell static IPs (the OP's and mine) are true static IPs; no DHCP, no PPP log in. (I also recall old threads about this.)
When I got the 4100B, I did an experiment to see if PPPoE would somehow work on my line. I was unable to successfully login with PPPoE on the modem, using a variety of settings. This further confirmed my expectation. |

| d_l  seems to think that the SS4100B could handle a true static in the half-bridged mode, "PPP is on the computer". I can't test this, not having a true static IP address.
The modem instructions state:
quote:
PPP is on the computer. This mode is normally used if you need to run a PPPoE client on your PC. This mode can be used with a gateway or router which initiates a PPPoE session. To return to the DSL modem user interface you will need to directly connect your PC to the modem without any gateway or router between the modem and the PC.
I'd guess that configuring the router WAN port with the static IP address data (IP address, gateway IP address, DNS server IP addresses) would be necessary.

As NormanS said, I do think "PPP is on the computer" mode might work with your true statics. That mode is even reported as a bridged mode by the modem. I usually call it a quasi-bridged mode because the modem is still trying to be a DHCP server for its single IP, 192.168.1.64., but there is no PPPoE encapsulation involved if you don't have a PPPoE client behind the modem passing that sort of traffic through it.
I'm not sure what advantage "PPP is on the computer" mode would give you though over the fully bridged mode. |

1 edit | But in the context of a single static IP on the WAN of the router as this thread is about, having the modem acting as a DHCP server isn't much help.  Edit: The modem DHCP serving is still mainly there for dynamic IP users. |

| I'll grant that it isn't much help, except if you want to check statistics. And if your ISP use DHCP to allocate an IP address, this could cause a conflict.
The other benefit is that PPPoE on the computer is the way an unconfigured 4100 will behave (because it doesn't have account info for doing the PPPoE). So, provided you are manually assigning the static IP address to router or computer, you would be able to just plug in the 4100 and it would work.
