| "UPDATE" DHCP on Z5 Problem
Ok NOT solved, same problem but I do think it has something to do with both the DHCP in the Z5 and the 3COM NIC used in the C series Dell notebooks.
Ok I must make emends.
After using a desktop with a 3COM NIC and the most recent driver for the card I successfully got the the Z5 DHCP to update the IP address.
I setup a Linksys SR41 using first 10.10.0.4 as the routers IP and handing out IPs in that range. With my Dell C610 connected to it I got 10.10.0.100. I then unplugged the cable from the SR and connect one coming from the Z5. The IP changed on the notebook to the correct Z5 range and the correct static DHCP IP. I then set the SR to 192.168.0.254, which is what my office DHCP server IP is, and got 192.168.0.100 on the C610. I then unplugged from the SR and plugged in the cable from the Z5. IP stayed the same, 192.168.0.100, and I had to do a repair and then got the correct IP. It was then I started a OLD desktop someone gave me a week ago and that I have just installed 98SE on with a 3COM NIC. Connecting the DT to the SR I got 192.168.0.101 and then connected it to the Z5 and the IP changed to the Z5 range, 192.168.1.110. That got me thinking about DRIVERS. I had the most recent driver for the 3C905C-TX family cards so I update the drivers on the C610 and NOW when I connect to the SR I get the x.x.0.100 and then when connecting to the Z5 the IP changes to the correct IP for the Z5. So this whole time it was the Dell driver that I had installed.
So anyone else seeing this same thing look on the NIC manufactures site for the newest drivers for your NIC and install them.

Decatur, GA | Just how would I know it was partly a driver problem. It did it on 3 notebooks and every time I connect to the office LAN the IP is updated to the correct range.

Re: "UPDATE" DHCP on Z5 Problem
I doubt the 3Com nic has anything to do with the problem. The DHCP bug is present in both Z-5 & Z-35 (firmware 3.64 and later) and in the P653-H (V3.40(OA.4)).
Every day I am typing "ipconfig /release" and "ipconfig /renew" regardless of the laptop I'm using (Dell D600, IBM Thinkpad T23 or Thinkpad X40).
My P653 and Z5 have a different internal subnet for the LAN segment and whenever I switch between the two I have to do the ipconfig thing on every single machine in the house, with nic's ranging from Intel's Pro 10/100 to Etherlink III and Broadcom's gigabit cards.
I am generally a very satisfied Zyxel customer, but the fact that this stupid issue had now been around for 6-10 months is really getting on my nerves ! Rather than getting this resolved it seems to be spreading to every device for which Zyxel releases a new firmware !
Especially on the Prestige 653 series that is frustrating, because the 3.4 0A.4 firmware introduces the DHCP bug and doubles the nr of VPN tunnels (and adds support for certificates, DMZ and static DHCP) at the same time... |

| said by jig  :bbarrera had one in an old thread. But according to bbarrera it is not a problem with the beta for this release firmware.
So the question is if he and shootist have the same issue.

| I plan on setting up 3 PCs, 2 notebooks 1 with the 3COM 3C920 (3C905C-TX compatible)(The Dell C610) integrated chip 1 with a Linksys Homelink HPNA/Ethernet PC card adapter (A IBM TP1400) and a desktop with a PCI 3COM 905 card, and do captures from all three switching between a Linksys SR41 and the Z5. The SR will have a IP of 192.168.0.254, same as my office LAN IP, and the Z5 with 192.168.1.1. This is where I have had the problem, I.E. when the NIC has a IP in a near/similar IP range. If I use a 10.x.x.x or 172.16.x.x IP on the other router the Z5 seems to reassign the correct IP to the PCs every time but I might also setup a third router with one of those ranges just to test. Now It's time to make some cables to do all this.

| The zw5 is being used at my day job (software startup) and we recently leased office space in Silicon Valley. We share office space with other startups and unfortunately we share a T1 and are behind NAT so no VPN yet (I installed zw5 after 10 hours at a trade show). As I normally work from home, testing zw5 is problematic at the current time. I'll be down there today and Thursday, will update firmware and try setting up VPN for remote access. I've got to talk with network folks to get permission to run wireless and VPN.
As of 2 weeks ago, no DHCP problems with 2 Apple PowerBooks (normally on 10.0.1.0/24 Apple Airport DHCP) and 1 Dell WinXP Pro notebook (normally on 192.168.110.0/24 Linux DHCP). That was with beta firmware that was released prior to 4.00(WZ.2)C0. |

| Well I don't see the problem when going from a 10.x.x.x to the default Z5 range. It is when it is something in the 192.168.x.x range but then last night when I did the test with the other desktop the Z5 DID assign the correct IP to it after it was connected to a 192.168.0.x router. This whole thing leaves me scratching my head and pounding on my forehead. The real funny, not really, part of all of this is NO matter where I take my notebook and connect it to a LAN it ALWAYS gets assigned a proper IP in the range of the LAN I'm connecting to except when I take it home to the Z5. %$#@@@*&.
I'm also going to check if maybe it's something to do with the Static DHCP assignments in the Z5 because that other desktop that DID get a IP change from the Z5 is NOT setup with a static DHCP assignment. It just takes whatever the Z5 hands out. In fact I'm leaning in that direction and would like to hear from the others that have posted about this problem if all there notebooks/PCs are using Static DHCP assignments.

Notebook @ home office (Linux static dhcp) = 192.168.110.88
Notebook @ remote office (Zywall 5) = 192.168.112.x
The zw5 is a basic setup (NO static dhcp assignments). |

That confirms part of my suspicion, NO Static DHCP!!! I think I may be on to something.
