Re: Viewing Modem Stats?
.254 - I was dyslexic and mistyped - thanks for the catch
That would probably work, but I am trying to do it without losing my PPPOE connection at the same time. If i change the router from PPPOE mode to static IP mode with any IP other than the one already assigned , I believe it will disconnect from Earthlink...
It may not be possible to do what I want at all, I know accessing internal private IP addresses from other private IPs does not work. |

| You can put a non-switching hub in between the modem and the router and run an ethernet cable to a second NIC card installed in your PC.
Not sure if that would actually work, either, since don't most DSL modems only allow one MAC address to connect on the modem's LAN side? |

That should work fine and one of those "ugly" ways to do it.
1) As Vpoko mentioned - 2nd NIC
2) Parallel router bridging across. I've been doing this with an old BEFSR41 (bridging a ZyXEL P314).
3) Replace router with one that can have 2 WANs with routing control.
4) The temporary solution I mentioned. |

4 edits | Sure thing. This is exactly how I've been running for a few years now. The trick is to NOT have LAN space conflicts (the LAN cannot be 192.168.1.x like the modem for example). The "ROUTE ADD" command must be added to any PC that has to talk to the modem.
Basically, the ROUTE command forces all 192.168.1.x to go to the BEFSR41 whose WAN is in the address space of the modem. Make sense?
EDIT: An added benefit. I can change the WAN of the BEFSR41 to PPPoE and pull a second connection from the ISP, too. 
EDIT2: Turn off LAN DHCP on the BEFSR41 if you rely on it (I never use DHCP so I forgot to mention it).
EDIT3: Instead of the added router, feed the added HUB/SWITCH from a 2nd NIC, use a similar ROUTE ADD for that NIC (which is set to 192.168.1.5) and you have solution 1). |

| Bill, I do something like that with this set-up. First with a rotary A-B switch (S) open, I make the PPPoE connection through the router, then I throw the A-B switch to close the connection to the network switch. This allows the modem's telenet interface to be accessed. This set-up works as long as the PPPoE connection is maintained. If it drops, the SX41 router can't make a PPPoE connection while the A-B switch isn't open.
Instead of the A-B switch, the cable from the router's LAN port to the network switch could simply be connected and unconnected. |

| LOL! GMTA! That used to work with my BEFSR41 but the P314 wouldn't tolerate the same ethernet address on both sides for some reason. In fact, it allowed me to find a bug/anomoly that was previously discussed in he ZyXEL forum because even when switching back and forth the P314 would get confused and a LAN port would be on the WAN even when it wasn't!!! I don't show a P324 I also have in this mix, too. |

| Bill, I think I like your arrangement better if I can do the routing with the SX41. I have an SR41.
The method I show above works just great when the PPPoE link is made, but if the link drops, then the mess begins. If the router tries to reconnect the PPPoE link on its own, the packets get into a race state and seem to just loop around continuously. Then I usually have to power-cycle everything to be able to reconnect.
I wouldn't recommend this set-up for a permanent network, but only for temporary modem tests. |

| I've been playing with Westell modems and they have the same old 192.168.1.1 requirement. However, they also have a backdoor utility that uses broadcast packets. Someday I'll figure out how the heck that would be possible with this arrangement - I don't theenk so! |
