Q: Linksys BEFSR41 V.2 - forwarding while DHCP serving y/n ?

[Grendel]

I know the doc says that you have to switch over to fixed IP addresses and turn off DHCP for using the port forward function. Problem is I can't switch off the DHCP functionality so I's wondering if there's a trick/setting that allows me to forward ports to a machine w/ a fixed IP outside the DHCP served range (my Zoom x5 at home just does it) ?

[Krom]

Set your DHCP to however many clients you want, starting at IP 192.168.1.25 or whatever, set the computer you want with a fixed IP address below that IP, then you can forward ports to that computer.

Or you can do like mine, max 25 IPs on the DHCP, starting at 192.168.1.50. My main PC runs 192.168.1.100, my server runs 192.168.1.200, laptop is 150, other computers are 101 and 102.

Thanks for the hints

Not working tho, tried a fixed address above and below the DHCP range. May be that Qworst account tho, not sure if they filter (they shouldn't..). Or the cisco DSL modem.. ICMP pings are disabled on the Linksys but I get a ping response if I try from home. Also ShieldUp on grc.com reports port 23 (telnet) being open (may be the modem tho). I'll have to look into that a bit deeper tomorrow looks like

Did you set up the static routing for the non dhcp machines?

[Avder]

Isnt there an option to statically assign ip addresses to clients?

[Grendel]

No routing, it's in gateway mode.

[BUBBALOU]

you have to manually assign DNS servers to each one of the clients and set each one with a Static IP.

On Router

Goto the DHCP tab and Disable DHCP Server, then go to the Status tab and write down the DNS servers from your ISP

On Client

Start with 192.168.1.50 for your statics and input the DNS servers on each machine

ENJOY

Thx Bubbalou, but

Have people w/ laptops working on the LAN that un-/plug a couple of times a day and also work on other LAN's. The DNS servers change from time to time too (thx Qworst -- Edit: not a real problem if I use the Linksys as DNS server tho).

No routing, it's in gateway mode.

where is your dhcp for your local network served from then?

try http://192.168.1.1/Routing.htm on the linksys to set up static routing. (replace the ip with your linksys addy). I think your meant to use static OR dhcp but as long as you keep the ip ranges seperate they seem to work at the same time.

the other thing you could try is "port triggering" in your forwarding or gaming section (depending on firmware version). http://192.168.1.1/PortTrigger.htm

You dont need to mess with the static routing to get it to work.

Router setup:

Forward the ports to the LAN IP (192.168.1.x)
Keep DHCP on.

On PC, don't do anything.

I do this and it works fine.

From the BEFSR41 V.2.

Hm, that's basically what I did before I posted Maybe the packets get blocked at the ISP.

Will poke around a bit in a while.

[Grendel]

Figured it out, thx for the suggestions. The Linksys works like everyone said, the problem is the Cisco 678 modem that has a NAT firewall build-in as well (kind of redundant ). This article got me going.

[Krom]

Ahh, yeah that would cause problems. Just forward all ports from that to the linksys, no need to use two NATs at the same time.
