[LARTC] Slashdot on WRT54G

[Ed Wildgoose]

Did anyone see the article?

It's the first time I really noticed that these little Linksys routers 
are such a fully fledged linux machine with a decent processor and a 
replacable firmware.  I am now itching to get one to replace the 
multipurpose firewall desktop machine.

Has anyone experimented with the current state of the firmware and how 
advanced you can get with tc rules?  For example is any of the l7 stuff 
incorporated yet? 

A 200Mhz processor and 8-32Mb ram seems butch enough for many small home 
and office firewall machines...

Hi there,

I do have one of the WRT54Gs and did contribute some scripts to James,
the head developer of the sveasoft firmware. I do not have the most
recent firmware since I had a few issues "subscribing" to the
development process but I still am thinking about getting more involved.

The web admin interface on the version of the firmware that I'm using
offers very little in the way of customizing the tc rules. However, all
you need to do to make them as granular as you want is to enable SSH,
ssh in and just copy/paste your script in. The firmware overall works
great though with my v1 router the processor gets maxxed out very
quickly if you are transferring files over the PPTP vpn. I know that
better access to the bandwidth management from the web interface is on
the development list.

Last I heard/read they are incorporating both the l7 filters and the p2p
wall projects.

It's an awesome product for ~6W of power and $70. There are 3 versions
now, v1, v2, and the WRT54GS. I believe the v2 has more flash and/or
RAM, the S model has the turbo mode for "108Mbps" performance. V1 and v2
have slightly different vlan/bridging setups between the wired and
wireless.

It sounds excellent.  The web interface is not interesting at all, ssh 
is the only way I intend to access it anyway.

Having l7 compiled in, but at least traffic control, sounds absolutely 
excellent.  If you can get it to run a vpn, then this is just superb

I assume you have a US model?  Can you tell me what sort of power supply 
it has?  I am thinking about getting one imported to the UK since they 
don't sell them here (and will probably be overpriced when they 
arrive).  Will a universal power adaptor work?  Also, any other issues 
with a uk ADSL line that might prevent this working...?

Thanks

The power supply is the standard Linksys unit. I can read off the exact
output of my adapter later if you want. The linksys specs say that the
power is 12V DC, 1A so that shouldn't be a problem at all. I have read
of people powering one off their car battery without much difficulty. A
picture of the power adapter can be found here:

I do have a US model but as long as your DSL modem has an RJ-45 ethernet
port on it you should have no problems. The only issue I can imagine
could be the MTU settings since here in the US some DSL lines have an
mtu of 1492 rather than the standard 1500 but that would be easily
configurable in linux if need be.

If your provider is using PPPoA instead of PPPoE then you might have
some problems. I'm not sure if the Linksys unit in default config
handles PPPoA. The only reason I mention this is because I know that
BT uses PPPoA.

Actually I asked what I thought was a silly question because I had 
naively thought that the WRT54G was also an adsl modem.  Having read the 
specs it appears just to be a wireless accesspoint with some firewall 
ability.

So I guess I'm curious how BT's choice of PPoA would affect things?  For 
sure their MTU is 1492 instead of 1500 (although I read they wanted to 
change that...).  But I would have expected pretty much everything else 
to be transparent apart from the abilities of accurately guaging speed 
with tc rules..?

Thanks for any insight
