help with static ip block

Hi people hope someone can help me here i have just got a block of 8 static
ip's from pipex i have a d-link dsl-504 router, when logging in i can only
use one of the IP's that pipex provided if i try giving the router any of
the other 7 ip's it just wont let me login ... is this right???

another thing can anyone help me setup or give me a URL that gives info on
how to setup the dsl-504 with multi static ip block, i have searched the
documennts that came with the router but its less than helpful in this area



thanx in advance

I don't know about your particular model, but the DSL-300T is retarded...
I don't hold my breath for any help from Dlink, but here goes.
You are at least a bit closer than me in that you can get one pc working-
I couldn't get anything working out of the box!

The 300T is a uClinux based embedded device- so a bit of Linux commands
gets me to where I need (though not perfect). If it is a linux based
device you should be able to login with the username "root" and password
"admin". (telnet to the 192.x.x.x host).

The output of "route -n" and "arp -n" and "iptables --list", and then t
might be possible to help out. The general steps I needed:
- add a route for 0.0.0.0 over ppp0 (wan port)
- add routes for all 6 useable IP's over br0 (bridge)
- add arp entries to point all 6 useable IP's to the correct arp of my
host.
- disable DLINK's firewall which blocks traffic.

My network setup is as follows, it should be possible to just put the
router direct onto a switch (with correct ARP detail), but I go via a real
Linux box with firewall and servers as I require. I'm able to use all 6
useable IP's from my /29 block.

If it really is a linux based box I might be able to help further with the
output of the commands above.

Adam well after a bit of messing arounf i got it to work first of all i had
the PPP set to static instead on unnumbered and io also had nat on which it
did not like as soon as i took nat off all the IP's work great oh i also had
to alter the ethernet IP to the one that the ISP gave me.... i thank you for
your input maybe if you still are running with NAT or a router IP of
192.168.*.* if you alter them i hope it might work for you too if you need a
more detailes please ask

After digging around a little more I don't think my piece of junk was
doing NAT, just loading the kernel modules (for some reason). If I had to
hazzard a guess I would say I have a router that's been adapted into a
modem.

Have you managed to use all the IP's on your own system without the
dlink router hogging one for itself?

I have a script that runs every 30 minutss which to check if the bridge is
still up and still doing sensible things (like sending Internet traffic
over the ppp link for a start), and reduces the MTU. (I found that it
would only alter the MRU not MTU- and ended up with a fair bit of dropped
traffic). The DLINK was sending out 1500 byte IP packets but then
discarding anything bigger than 1384 bytes. How are remote sites going to
know that I'm going to trash packets >1384.

I think I'll leave things as they until I get an hour or two spare to
investigate it properly. But thanks for the feedback.

(Besides my way I stop the status light blinking- I can't be the only
one that associates blinking lights with broken ;-)

teeno:
The official D-Link info for a Non-NAT setup on the DSL-504 can be
found here:
<ftp://ftp.dlink.co.uk/dsl_routers_modems/dsl-504_rev_b/>

The best site for all info on the DSL-504 can be found here:
<http://shadow.sentry.org/~trev/dsl50x.html>

Since it's been mentioned, the DSL-504+ runs an embedded OS called
ATMOS from GlobespanVirata (now part of Conexant).

If you do need to telnet in, the password is the SNMP 'Write'
community string, which by default is 'private'.

Adam:
You're not wrong - all the new "T" series models have similar
internals, running firmware with much common code under the BusyBox
embedded Linux kernel.

There have been several (3?) firmware releases to get rid of silly
things like "NAT on a modem" which you describe. Find software
updates here - the current one dated 18-Jun-04:
<ftp://ftp.dlink.co.uk/dsl_routers_modems/dsl-300t/>

Hope this helps

Unfortunately I'm running the lastest firmware. I think I'd rather the old
firmware, at least that managed to get a default route over ppp0.

I'm not holding my breath for Dlink to offer any kind of support.

thanks anyways.

Adam the dlink has taken one of the IP yes but i guess that is better than
only been able to use 1 of them ... i am sorry to hear you are unable to
solve your issue at the moment lets hope dlink can help u and i guess many
others in the same situation

Can you please let me know what steps you had to perform to use your
/29 block with the DSL-300T?

Thanks,

Chris
