Anybody know anything about setting-up a SPAN/Port Mirroring on a DD-WRT router? I see lots of people asking on to do it on the interweb, but haven't found an answer yet.

TIA

I've never had a VLAN at home so I have never had to try and use the feature.

Also, I changed to tomato today because I like the interface better.

I wish I could help more.. What are you trying to do with the mirroring?

I'm playing around with a few SIP phones; wanted to look at all the messaging in between. Wireshark does some cool stuff; will even analyze & piece together the captured RTP packets and play back each leg of the conversation for you.

For now, I ended-up using a hub to capture everything which isn't efficient, but works.

I just obtained WRT54GL today and got DD-WRT on it, so am new to the custom firmware thing. Mainly using it for bridging a wireless to LAN connection at the moment.

Haven't heard about Tomato. Does it offer any functionality besides the different web interface? Is it as easy to install as DD-WRT is?

Thanks.

Just looked-up tomato. The statistics monitoring do look much improved over dd-wrt. May have to try it out as well.

If you are serious about the Port Mirroring or SPAN you should look into OPENWRT - if it's not there I imagine it can be added to the image.

I like DD-WRT and I am enjoying the newest release v24, but it still have issues with N support and the last time I checked Tomato didn't support N devices at all.

Just curious...but what are some of the reasons you guys switched from the standard interface to DD-WRT? I've seen alot of people who have switched, but wondering if there's any huge advantages to it?

TIA!

My reason for switching was for PPTP VPN server integration, advanced port forwarding/mapping, vLAN support, more wireless options, ability to increase power output, ability to switch between repeater/WDS/AP/Router, local DNS, Bandwidth monitoring and significantly better QoS.

It really can take a $60 router and put it on par with some of the much more expensive pieces of equipment.

Thanks for the info sellis. I've been looking into doing the mirroring with iptables, too.

KWarner, my main draw to using DD-WRT was for the WLAN to LAN bridging. Also, just like messing around with all the additional features over what the standard firmware provides.

Like sellis said, DD-WRT or the other flavors of firmware really provide you a lot of the functionality that a more expensive managed switch or router would, for free.
