Help setting prestige 645r

[RustyNale]

Hi. I'm trying to get a prestige 645r to talk to a linksys router, with the linksys handling dyndns for rdc. I have 2 users who want to access their network at the same time and the prestige will let me set up the port forwarding to 2 comps on the network, but the access will only work for a short while, then only let one user connect. I've setup port forwarding to the standard port and set a second ip to use a diff port number. Unfortunately, the prestige is only accessable using telnet and is a real pain to configure. Anyone have any experience with this model? Ideally I'd like to make it act just as a modem and let the linksys do the routing...

I've got a Zyxel Prestige 643 - I'm not sure what the differences are. I've also seen it do some flaky stuff like you describe. One thing I did in a similar situation was to set it up with a static route so that my Unix box could do all the firewalling, natting, and routing. On the telnet menu I'm looking at that's option 12. So basically you'll get something like...

DSL-->(public_WAN_IP)-Prestige-(10.0.0.1)-->(10.0.0.2)-Linksys-(192.168.0.1)-->(192.168.1.x)-PC's.

Then, in the Prestige, you set a static route to 192.168/16 via 10.0.0.2. You set the Linksys's gateway to 10.0.0.1 (the Prestige). You set the PC's gateway to 192.168.0.1 (the Linksys). That will basically make the Prestige do nothing but ferry packets over to the Linksys and let it do all the work.

Overall, the router's really a POS, though. It may very well do strange things even in that setup. I'm only using mine at the moment because one of my furry feline friends took out my Cisco by knocking it off my desk.:|

cleverhandle, thanks for the reply. For this model, it looks like it would be option 12. Looks like it might do it, but I won't be able to try it till Thursday 🙁 Thanks again!:thumbsup:

No problem. One other thing...

You should be able to do this, too, if the Linksys supports PPPoE (which it probably does). You can set up the Prestige in "bridge mode" in Option #1. Then the Prestige basically just takes the raw signal and changes the media from a phone line to Cat5 - you would then need the Linksys to handle all the authentication and IP negotiation.

From a logical standpoint, this is simpler than setting up static routes. But practically, I recall it being a bit fussier to set up in the menus - you may need some other options besides the main one in Option #1. Also, it means you won't be able to access the Prestige via telnet because it wouldn't have an IP anymore.

Dude, it worked! You rule, thanks for the help 😀

You're welcome. Glad to hear things worked out.
