Just noticed this in the router logs. Anyone know why Hardware NAT would be off?

Hardware NAT: Disabled
Software QoS: Disabled

Do you have ipsec passthrough enabled? That will disable hardware NAT as it is incompatible with it.

reets · 2012-06-12, 09:37 AM

That was on, disabled it and rebooted the modem. Hardware NAT still shows off. Do PPTP/L2TP have to be off too?

Maybe. I can't remember, it's been months since I looked at that.

reets · 2012-06-12, 12:15 PM

Fixed it. Had to disable L2TP and IPSEC passthrough. Also had to disable wireless multicasting.

If you go to "Advanced Settings > LAN > Route tab", even if "Enable multicast routing?" is disabled you still have to set both 2.4GHZ and 5GHZ Multicast Rate to "Disable" for it to work.

I know this might not be the best place for this but this is where the N56U experts are. Has anyone been able to use Rogers One Number service with this router? I tested it with another connection and it works fine but this router is blocking something.

I DMZ'd my pc and still no go (also tried opening various suggested ports from other posts around the net with no luck).

If this post is deleted, I understand.

I want to remotely administer my RT-N56U from my computer which is plugged into a router that is plugged into a LAN port on the RT-N56U but I just can't get to it. No problem with the computer plugged directly into that port and no problem logging into another router from the same configuration on the same subnet.
Also no problem logging in from the from the WAN side thru port 8080.
Are there some special settings that I have missed in the documentation?
The only difference I can see is that the direct connect gets it's IP from DHCP on the RT-N56U whereas the indirect connect gets it's IP from the middle router. Does this make the difference?

@castlestone

You should disable the DHCP on your second router and let the RT-N56U handle it, unless you have some very specific reason for needing multiple DHCP servers.
That will fix your problem the easy way.

2 dumb questions (my brain isn't working right now).

1. Can I disable the router functions on the N56U and use a 2nd router to manage devices?

2. If #1 is possible, will the TV's plugged in via eth still work plugged into the N56U?

1. You can disable the DHCP server sure... as long as you hand out the IP address of the Asus as the gateway and have one network. Otherwise you can DMZ another router and double NAT things. It depends on what you want to achieve.

2. Yes.

A few questions to lob over the transom. I have never kept up with consumer routers. At home I've been running a BSD based router on a somewhat older machine and am tempted to retire it from that purpose. I've got pf running on that box.

We run a mostly wired network here at Casa Tandem but I do have to support some wireless devices - my sons' phones (no net plan for them) and a couple of laptops. Everything else sits on the wired lan driven by a 24 port switch. The Asus would fill our routing and wireless needs just fine.

Moving the router functionality is straight forward enough; is there any chance I can use some of the spare CPU cycles to run other services? I'm wondering if this unit, or something else you can suggest, could be configured to support Squeezebox slimserver or whatever Logitech now calls it, or DLNA, or simple file serving. It'd be easy to power down the old noisy server (even if it is in the basement) if I could find a home for our audio files which need to sit on a 24/7 machine.

After reading the first post I was intrigued that the CPU in this router has plenty of headroom.

Any thoughts?

File serving using samba, FTP access, and UPNP/DLNA are built in services. Logitech Media Server is a definite no-go. Just not enough space, CPU, or RAM.

Double NAT wouldn't work since it's definitely the ASUS that is blocking the Rogers One Number service. DMZ and even trying through a VPN didn't help.

I'll give it a try tonight and see if changing back to my Netgear router helps. Thanks for the answers file.

Boo! Looks like my Netgear WNDR3700 doesn't allow for just setting the default gateway (unless I'm understanding things wrong when you say "hand out the IP address of the Asus as the gateway").

Okay, step back and take a deep breath. You are making about as mess sense as Rogers long term planning. If you are attempting to eliminate the Asus from the equation to try to get Rogers One Number working then the only way to do that would be to physically remove it and replace it with something else, or wait for passthrough support to bubble to the top of my list.

If your VPN attempt forwarded all traffic through it then that's interesting... cause the Rogers One Number packets wouldn't have been visible to the Asus router really, and it shouldn't have interfered.
