Zywall 2+ and WRT54GL

We're wanting to use the linksys switch for more hosts on the same LAN (switch only? No firewall/NAT on linksys?). Can we link (uplink?) wrt54gl with the Zywall somehow where pcs connected to the linksys will still be firewalled by the Zywall?

Will we still be able to use the wireless AP with this config? Willing to use different open firmware for linksys if needed (openWRT, tomatoe or dd-wrt). Should be able to use stock firmware for this?

Sorry, but it's been awhile. This should be simple so why am i not getting a plan here.

Thanks for any help!

Sure turn off DHCP serving on the linksys and plug a lan cable from the zyxel to the linkys. You will get out of the deal 6 ports vice 8 though because your 'using' one port at either end.

THis is applicable as the linksys is also has a radio, so you can setup a switch and AP......

Awesome Anav! Thanks for those links! Need to shake out the cobwebs ;)

If i further understand correctly, another feature of the Zywall: [if needed in future] We can setup WLAN separate from LAN using the WLAN mode on one of the ZW ports and plug the Linky there? Would the other linky ports utilise the Zywall FW doing this? Pretty sure we'd need to change IP on linky for this also? And then of course, unless clients were all setup statically we'd need DHCP [from linky?] again?

Thanks again Anav so much!

Re: Zywall 2+ and WRT54GL

The zywall 2plus has two other zones which you can use much like the LAN. They are firewalled off with full flexibility and are DHCP serving. They are called DMZ and WLAN but your better off thinking of them as zone 2 and zone 3. Yes, to protect your private LAN from guests or kids heheh, suggest putting them on one of the other zones. Correct, you designate which of your four ports on the zywall will be zone specific and cold reboot the router into this configuration. All the PCs will get their DCHP from the zyxel according to what you have setup for that zone. I would make the ZONEIP static on the linksys to match, ie the linksys LANIP (dhcp serving off on the linksys). For ex. if the zone gateway IP was going to be 192.168.2.1, and it started handing out IPs at 2.33, setup 192.168.2.2 for the linksys LANIP. Goes without saying connect lan cable from zone specific port on zyxel to lan port on lynksys

Yep... The Z2+ is great... I use it with a Belkin Wireless N router (with DHCP and routing disabled). So it adds access point capabilities and extra lan ports... all behind the Z2+ as the firewall/router.

I realize your using the Belkin and not the Linky, but perhaps you can tell me if these settings are on the right track: 1st, are you using your Belkin via the ZW WLAN port or as ANAV mentioned above?

Here's what i will try without using WLAN mode on ZW:

LINKSYS SETUP:
disable DHCP
Operating mode: Router (not Gateway - i believe i'd have to setup a static IP for Linky from here or in Basic Setup or let Linky dynamically set?)
RIP disabled (is this what you meant by "routing disabled"?)
Firewall disabled (since it's behind the ZW)

Thanks again everyone!

Well i thought of another question. If using the WLAN port mode on ZW, would we still connect (from ZW WLAN port) to LAN port on Linky? or WAN port on Linky?

Re: Zywall 2+ and WRT54GL

You need to read the faq again and the advice.
Your using the second router strictly as an AP/Switch and NOT a router.
Therefore you do NOT use the wan port on the AP/Switch (belkin or linksys etc) but DO plug into one of the lan ports.

In the AP/Switch the only selections you really have to worry about are the following two
a. turn off DHCP serving on the lan side
b. assign a LANIP to this unit that is within the subnet of the primary router (the zywall) and preferably outside the automated pool of IPs given out by the router.
For ex if the zyxels lanip is 192.168.1.1, and it assigns IPs starting at .33, then assign a lANIP to the AP/Switch 192.168.1.5
You may need a subnet mask and 255.255.255.0 works for me.

That is the general case above, but you do not want to attach this to the LAN, you want it separated and attached on the WLAN zone or DMZ zone. Plug the lan cable connection from the AP/Switch to the assigned WLAN or DMZ port pre setup on the zywall. Remember the lanip you setup on the ap/switch should match the zoneIP setup in the applicable zone.

Anav, with most Belkin gear Belkin provide the ability to run the gear in dedicated AP mode and in that mode the Belkin WAN port converts into a LAN port. There are some [few] other OEM's that also do that kind of thing -- so on Belkin gear the WAN port can be used as a 5th LAN port assuming that the Belkin configuration has been adjusted appropriately. :)

Re: Zywall 2+ and WRT54GL

Sorry I've been away for a while. My Belkin is in fact running in AP mode, so its WAN port connects to a LAN port. I guess to be 100% truthful, I have a Gigabit switch and the Belkin WAN connects to a Gig LAN switch port. Likewise a Z2+ LAN port connects to the Gig LAN switch as well.

I do use the 10/100 meg LAN ports on the Belkin and the Z2+ as additonal LAN ports for lower speed devices if needed (printers, etc.).

Hey mozerd !!!

That belkin Pre-N is still running flawlessly in AP mode. Takes a licking and keeps on ticking 24x7 month after month.

Thanks for recommending it all those years ago. :D

That True MIMO technology is outstanding -- still beats the heck out of anything else in the current marketplace.

In February of 2010 Qualcomm [who now own Airgo True MIMO] will have a 4x4 True MIMO wireless system that should ROCK the wireless world .... :)

Glad that you're making good use of your AP.

Re: Zywall 2+ and WRT54GL

Wow, it's taken a long time to get back to this thread! Just wanted to update and thank everyone for their input.

Working like a charm whether i need a wired port or wireless! :)

Haven't tried the WLAN port (Zone ?) 'cause no need to keep separate from LAN (yet) ;) I'd like to try that someday soon tho. I'd also like to know about "AP Mode" with this unit using stock fw, and what benefits - if any - are gained. Guess that's a question for the Linky area.

Again, thanks for everyone's help on this. It actually was so easy a caveman could do it. (ugh, sorry 'bout that one) :)

Now since everything works so great i plan to mess it up by flashing with DD-WRT FW. But i think i'll wait on that. I've always wondered what it brings to the table that the stock fw doesn't. But i guess that's another question for the Linky area.

Aloha Anav! Sorry, i meant to ask you if the older ZW2 has these same zone port options that the ZW2+ does?

Thanks

No, Z2 has only one LAN and two IP aliases.
