Re: [Modem] out of the blue PPPOE problem! said by rxb216:I do it this way cause I do a lot of port forwarding, and I dont think port forwarding works if modem does the pppoe authentication If you use the public ip option that's on the motorola's connection configuration page and set the routers internet connection type to automatic port forwarding will work |

Santa Clara, CA | wayjac,
thanks for the info. so to confirm, if i put PPPoE back on the modem and enable "use public IP address" in the modem GUI, i can do the following:
1. Port forwarding
2. DDNS, will the dynamic dns service that is built into the d-link router work?
Located here: »support.dlink.com/emulators/dir6···dns.html
Other than that are there any disadvantages I will have by leaving pppoe on the modem, rather than the router?
Will programs on my clients that use UPNP be able to open ports and work properly? just want to make sure that the modem has no firewall or port blocking capabilities (I just want my router to do that) |

| If you use the "use public IP address" setting in the modem, and use DHCP on your D-Link router's WAN interface (you may need to power cycle both the modem and the router to activate the setting), the modem will emulate being a dumb bridge modem and your D-Link router's WAN will appear to be directly connected to the Internet.
Whatever UPnP or other method you used when the D-Link router was doing the PPPoE authentication should still work exactly the same way. The biggest obstacle may be that your router is not compatible with the modem in this mode. I have found that occasionally a router will not work with an AT&T modem in IP passthrough mode just as some routers are not compatible with doing the PPPoE authentication with AT&T modems. For example, I was never able to get either my Linksys RV082 or my D-Link DI-LB604 routers to work with IP passthrough with any AT&T branded Motorola, Westell, or 2-Wire modem that I tried (the DI-LB604 would work with a Netopia 2241, but not with any other Motorola/Netopia model that I tried). Hopefully you will have better luck.

With the modem doing the pppoe and also set to use the public ip
You can forward ports with the router
The router will have a public ip address and ddns will work
said by rxb216:are there any disadvantages I will have by leaving pppoe on the modem, rather than the router? No, not with this setupsaid by rxb216:Will programs on my clients that use UPNP be able to open ports and work properly?? That depends on how well the routers upnp works |
