    How is everyone? (Missing you guys)

    Prepare yourselves (for I am a woman and need to let off steam occasionally).....

    It's been crazy of late...been helping offices move sites, installing switches and making up loads of network cables, patching allsorts...

    Latest is been trying to get a sites router working - you'd think it'd be really straight-forward as they have a firewall, and the firewall routes to a server that has DHCP...so you should just be able to disable DHCP and the firewall on the new router, then connect it to the firewall (Plus enter service provider account details/password)...and bobs yer.....NO SUCH THING!!!

    Spent three hours configuring it last night - setting up with a fixed internal ip, then NAT and stuff cos it wouldn't see the firewall (so figured best way is to make the router pass everything to the firewall internal ip), but today still no joy:

    I looked at, rather than assigning the router a static ip, just letting it automatically pick up an ip...it did, but it picked up the ip that the firewall is set to (static) and the firewall has a vpn connection to another site which is working perfectly, so don't want to do anything to that...

    ...then I phoned service provider and asked if they could change the framed ip address from the one that was being dished out to a slightly different one (one of 5 assigned to the line)so the router would pick this up instead of the firewall one when set to dynamic.. and they said that unfortunately this can't be done...

    They then talked me through changing the ip address settings on the router - they asked me to set the LAN ip to the the external ip that was being assigned (Thought that odd, but assumed they knew what they were advising), and once this had changed, I was unable to even get to the router to configure it!!! (may have worked i suppose if there was someone connected to the internet and accessing externally, but I was in a cupboard sat on a hoover under the stairs (LOL) and had no such privelidges (spelling!!) as staff shortage at work for a week or so...

    ..so then I have to put everything back as it was when I started...luckily it was reasonably straight forward...but craziness I tell ya!!

    Does anyone know of any routers that would be good for just acting dum (passing the ADSL through and nothing else)...if so, please do tell

    ...(X modem springs to mind??)

    Cheers,

    L

    And the moral of the story...always back up your original router configuration before changing it (or having someone help you to change it). You never know when you might need to restore it.

    Sorry you've had such a tough time, but I suspect that's "business as usual" in the Land of IT.

    It sounds like you have an SDSL installation from the information about 5 IP's. You would assign a public IP to the router if it was the first bit of hardware after the DSL router or if it was behind a switch. But if you have a firewall in front of the router then it should have a private IP to match your network.

    Do you have an option to assign an IP for the gateway on the router? You should point this to the firewall, but I guess you have already tried this. 8)

    EDIT: Actually read your post properly and it's not SDSL, you very obviously stated that you are using ADSL. I'm quite hung-over right now so that is my excuse!

    As for a dumb router, not sure of your budget, but the Cisco 871 will do this for you. What sort of router are you using at the moment?

    Yeah, bit of a hard one that. Took over the move at the last minute 9the day that it was going ahead)...ah well, best way to learn is from your mistakes!! (at least that way, we have to learn how to do it)

    Thank you...

    You're welcome. I had an instructor in one of my Cisco classes drill that thought into my head and it saved me more than once...at least in a classroom environment. :wink:

    It sounds like the guy on the phone was trying to get you to bridge the connections, what router and firewall are you currently using?

    If the firewall has a published IP then it looks like you can assign another static IP to the router and away you go. If the firewall only has LAN IPs then you may have to configure NAT on the router.

    Also if you switched the router with the new one without rebooting the firewall the arp cache will still have the MAC address of the old router. You may have the option to view and then flush the arp cache in the firewall. 8)
