Re: [BC] TELUS (Siemens) SE567 brdbnd (ADSL) wireless gtwy as hu
Sorry about the long lag on getting back to my thread ... I do appreciate the help and am just trying to figure out the best way to diagram my network so others can visualize what I've got going on here and possibly recommend what to change, configuration-wise, if anything, on the SE567.
While I draft a detailed diagram in case it's needed, here's a written overview:
- my ADSL modem is the Thomson speedtouch
- the speedtouch connects to one of the LAN ports of a D-Link DI-604 E1 (acting as a 100Mbps switch, DHCP definately disabled)
- the Linksys BEFW11S4 V4 (my intended primary [& only?] 'router') connects to another of the LAN ports of the D-Link DI-604 E1
- a server PC connects to another of the LAN ports of the D-Link DI-604 E1
Note: with my residential enhanced high speed plan (3Mbps), I can pull down 2 dynamic IPs from TELUS - one for the server PC and the other for the BEFW11S4 V4, which in turn feeds various PCs through a 6-port 10Mbps hub, a 4-port 10Mbps hub & specified-MAC, WPA-PSK wireless-B.
The above arrangement has worked well for some time now.
So, what I have introduced is the SE567 as a downline 100Mbps switch ... to eliminate the 4-port hub 10Mbps bottleneck in my living/dining room area. Using the SE567 as a wireless-G WAP is an added bonus.
Even if I could figure out how to disable DHCP on the SE567, I believe I need to leave it enabled for wireless-G clients ... no?
couttsj ... if I understand you correctly, ports 1, 2 & 3 of the SE567 are not, strictly speaking, identical in nature (you say specifically to use port 3 for the Linksys BEFW11S4 V4 - why would that be?). This latter aspect I do not get (yet) ... I thought I should only avoid port 4 (the WAN port) of the SE567.

This latter aspect I do not get (yet) ... I thought I should only avoid port 4 (the WAN port) of the SE567. The only difference between a hub and a switch is that a hub transmits all packets to all ports, whereas a switch has the ability to learn the IP address of the connected equipment and transmit packets only to the intended destination. There is a misconception that a switch is more efficient than a hub, but the difference is extremely marginal on a small network.
Port #4 on the Siemens router has the ability to act as a LAN switch port, or a modem WAN port if the ADSL port is not in use. The other 3 are just normal switch ports. I only chose #3 port to make the diagram more orderly. What I did discover is that port #4 cannot be used to piggy back to another hub/switch. | |

| I see ... well, I'm learning quite a bit from you couttsj ... and I thank you for that ...
I take it then that my original intended use of the SE567 would have been as a 'switch' ... as opposed to a 'hub' ... except that now I also want it to be a WAP and may need to leave DHCP enabled, thus, the SE567 would now be functioning more as a 'router'.
Would you say that DHCP should / must be left enabled on the SE567 for WAP (wireless-G) functionality?
Can DHCP even be disabled on the SE567?
- if so, I cannot immediately see how to do so.
What, if anything else, would you say I should do with the SE567 config?
I have its' firewall turned off, my rationale being that it is behind the BEFW11S4 V4 and should not require this level of protection, however, this security hole still gives me pause for thought.
I have noticed that the SE567 is unable to establish system time for itself (ie. for the System Log), very likely due to having no ADSL internet connection.
From a useability / security standpoint, does it matter which router is handing out IPs? The current situation where the SE567 typically beats the BEFW11S4 to the draw (DHCP IP address allocation-wise) doesn't immediately concern me, however, it just seems messy overall.

The only configuration information I have is what was supplied by Glowduke. In that configuration, the SE567 was the first router using port #4, with another router plugged into one of the other ports. He did not say if the wireless was still functional, but I suspect that it is.

said by Frankenstien :Can DHCP even be disabled on the SE567? - if so, I cannot immediately see how to do so. Yes, but it is not necessary to do so. You can use both simply by using fixed IP addressing.
said by Frankenstien :What, if anything else, would you say I should do with the SE567 config? Use fixed IP addressing where possible. Whenever you are using 2 networks (2 public addresses), make sure that you define 2 networks properly using the IP/Netmask combination. For example, 192.168.1.0/255.255.255.0 defines a network of 254 addresses (the first & last numbers are unusable). 192.168.1.0/255.255.255.224 defines a network of 30 addresses (192.168.1.31 is the broadcast address).
said by Frankenstien :I have its' firewall turned off, my rationale being that it is behind the BEFW11S4 V4 and should not require this level of protection, however, this security hole still gives me pause for thought. No comment.
said by Frankenstien :I have noticed that the SE567 is unable to establish system time for itself (ie. for the System Log), very likely due to having no ADSL internet connection. Correct, it has to be connected to one of the public addresses.

The current situation where the SE567 typically beats the BEFW11S4 to the draw (DHCP IP address allocation-wise) doesn't immediately concern me, however, it just seems messy overall. As I stated earlier, you don't need to worry about DHCP on the private network if you use fixed IP addressing. On the public network, you have no choice; you have to use DHCP. Fixed IP addressing is more reliable, and the routing is consistent. | |

| couttsj ... thanks for all the help eh?
I'll search out Glowduke's SE567 threads / posts and see what else I can glean about using this gateway device as a switch / WAP, whether I should pursue disabling DHCP on it (still require specific procedure) and any other configuration changes worth making (ie. re-enabling firewall and enabled level).

| WOW. I will have to dig out the books on the SE567, but I believe you can not turn off the DHCP service(s) of the device. I will double check. The WAN port of the SE567 is designed to learn an IP address to which it transmits the packets upsteam, etc. However will retain a Private networking set up, ie, 192.x. Thus giving IP addresses to MACs as they request IPs, etc.
As for the WAP, unless we can turn off the DHCP service, will remain assigning IPs within its range. I will have to check further on this device. Hopefully I can respond with findings by Mid-afternoon on Friday.

| WOW, I am sorry about the delay. I have been a bit busy over here. Anyhow, I dug out the Siemens and tried to muck with the settings, it is not an easy device. I believe that what we are trying to achieve is beyond the scope of the device.
The Siemens does not allow the DHCP services to be shut down. So it will retain private networking and support IP's within its DHCP range. Reading that your intended purpose was to use the Siemens as a 100MB Switch in your dining room, I think we are left to purchase a Simple Switch at 100/1000MB Speeds.
Good Luck, let me know if you have more ideas.
