Easy DHCP & MAC question for those in the know!

TheBigCheese · 13 Dec 2012 at 14:44

Hi all

I've just bought an ASUS RT-N66U and haven't got to grips with it yet (noob - eager to learn!), looks amazing though!

Anyway I need to link it up to my credit card machine so I can accept card payments through broadband instead of needing a dedicated phone line.

Two of the critical features I need to answer which I'm not sure of are:

DHCP has to be enabled
MAC filtering has to be disabled

Can anyone in the know just tell me how I can check they are as they should be please.

If I get this wrong I'll bork the credit card machine setup :eek:

so I need to get it right...and I need to get it sorted today if possible as merchant services are waiting for me to get back to them...

Anyone any ideas?

Thanks!

Sorry to bump, just wondering if anyone has an idea about this - Asus RT-N66U, how do I tell the DHCP and MAC settings?

I've tried on the Asus forums but they keep timing out due to being busy...bonkers!

Thanks!

Thanks for the reply.

I've just noticed sub tabs in some settings...I've found in LAN the DHCP Server, it is showing as enabled...is that it?

Thank you both for your replies.

I think that's the DHCP sorted then.

I think I've found the MAC stuff you both mention regarding filtering, under the same setting LAN - DHCP Server, there is a setting for:

Manually Assigned IP around the DHCP list(list limit:32)
Under that it shows MAC addresses, IP addresses with add/delete and the table is empty.

Would that be that?

chris6273 - there doesn't seem to be mention of MAC in the firewall settings, everything is pretty much set to off, except for the general firewall being enabled.

Thanks for the link Rroff, but I think I'll stick to an out of the box solution until I understand what I'm doing with the router, I'm very green with it at the moment so wouldn't benefit from changing, I have just put the latest firmware on there though...that was painless doing it from the router web page!

DHCP is usually on by default, and Mac filtering is usually disabled de default.

Mac filtering refers to the ability to restrict or enable access to the network based on the mac address of the card. Each network card (or NIC) has its own pre determined mac address and you just enter this in the list to enable or diable access depending on the set-up.

The "Manually Assigned IP around the DHCP list" Just means you can make it so a computer will always obtain the same IP address (DHCP) from the router by using its MAC address.

Hope I have explained this in a way that's understandable as I'm confusing myself here.

I was right with you there until you put that last line in and I lost all confidence in the rest of your message!

Thanks for the confirmations folks.

What card terminal (make/model) do you have and what acquiring bank (Streamline, HSBC, Lloyds Cardnet, etc) are you with? I work in the Merchant Services industry providing technical support so should be able to help you.

Wow, thanks very much!!!

It's a Gemalto Magic3 X-8 and it is with Streamline.

You know I've always thought that the OCUK community could form some sort of underground community, we all have skills in so many areas, your post has confirmed it!

Thanks for the detailed reply.

Sorry I've been a while replying, it's been an utterly crazy day today!

Yep DHCP is on, ummm...not sure about UPnP...any reason why it wouldn't be by default?

It's working fine, it's currently still on the phone line as normal.

OK, again I'm not sure how to open those ports (if I need to) so I'll cross my fingers! It will hopefully be live by the end of next week so I guess I'll see how it goes.

Aye, it is an old machine now...it's pretty chunky! I've had it a few years and haven't been offered an upgrade at all...they'd probably try and push me into another contract if I asked!

It does the job so I can't complain really.

What they don't seem to do which I find a bit weird is just have a wifi terminal...not bluetooth, not mobile, just standard wifi to connect to a router. It doesn't need line of sight like a bluetooth does, it doesn't need a good mobile signal and it's wire free.

Streamline didn't have a clue when I spoke to them about it and 123Send couldn't help when I enquired about terminals there.

Bit rubbish really.
