hmm I want to try this but i dont know which router to buy that would support the bandwidth ill be pushing

currently i have 2 modems connected to two NICs in my pc and they both work for the most part anyway each modem is 30/10 mbit yeah comcast is nice Smile anyway i download at times up to 7MB/s so I need a router that can keep up, can anyone recommend one and that is also supported by this firmware? its not always easy to find the max throughput for some routers so i'm hoping you guys can chime in with your experiences

Would this be possible with three different types of DSL modems, I have got VDSL2, ADSL2+ and ADSL2+ bundle modems two of them in the same ip range?
I would like to try this with my WRT54G v2.2 if it's possible. I'm running v24 sp1 on the router.

I feel kinda dumb asking this but is there a noob guide on how to set this up? I'm not sure how to install the scripts into my router. I'm pretty knowledgable about things but this has me a little lost... but then again I haven't sleep for a while ether lol. Could you guys please help me set this up? I can't figure out how to upload the scripts, it's not like solaris or dos in the telnet window so I'm kinda lost on how to get this running. Any help would be greatly appreciated and this would be awesome.

Bump!
Finally after many failed attempts with DHCP I managed to get the thing working with both routers with static IP (with DMZ in each one).
Downloads are lightning fast, but when I use P2P everything lags down so, my question now is: How should I set QoS?

I've two DSL connection of: 3 Mbps Down / 256 Kbps Up (each one).

Should I set Uplink in QoS with 85%~90% of Uplink wan1 + Uplink wan2?



Thanks.

Hi everybody,

Finally I get dual wan running correctly on my wrt54g-tm (v24-sp2 01/10/09 std-nokaid) with the help of Jbarbieri scripts, using 1Mbit adsl and 1.4Mbit 3G broadband.

Here are my settings if anyone is interested :-)

nvram set vlan0ports="3 2 1 5*"
nvram set vlan1ports="4 5"
nvram set vlan2ports="0 5"
nvram set vlan2hwname=et0
nvram commit
reboot


wan2.firewall script

#!/bin/sh

WAN2_IFNAME=vlan2
WAN2_IPADDR=192.168.1.2
WAN2_BROADCAST=192.168.1.255
WAN2_GATEWAY=192.168.1.1
WAN2_NETMASK=255.255.255.0

if [ "$(nvram get wan2_ipaddr)" != "$WAN2_IPADDR" ]; then
nvram set wan2_ifname=$WAN2_IFNAME
nvram set wan2_ipaddr=$WAN2_IPADDR
nvram set wan2_gateway=$WAN2_GATEWAY
nvram set wan2_netmask=$WAN2_NETMASK
nvram set wan2_broadcast=$WAN2_BROADCAST
nvram commit
fi

ifconfig $(nvram get wan2_ifname) $(nvram get wan2_ipaddr) netmask $(nvram get wan2_netmask) broadcast $(nvram get wan2_broadcast) up

Then,

cd /jffs/
wget http://www.jbarbieri.net/dd-wrt/scripts/iptables
cd /jffs/scripts/
wget http://www.jbarbieri.net/dd-wrt/scripts/firewall.firewall
wget http://www.jbarbieri.net/dd-wrt/scripts/routes.firewall
wget http://www.jbarbieri.net/dd-wrt/scripts/udhcpc-wan2.script

chmod 755 /jffs/iptables
chmod 755 /jffs/scripts/*

nvram set rc_startup='/jffs/scripts/wan2.firewall
/jffs/scripts/routes.firewall'

nvram set rc_firewall='/jffs/scripts/routes.firewall
/jffs/scripts/firewall.firewall'
nvram commit
reboot


Here are some outputs:

I'm running a Linksys WRT54GS v.5 with the DD WRT 24 sp1 micro generic on it. Am I going to be able to do dual wan with this one? Or do I need a different router?

Nevermind I think I got it working =) I changed my firmware back to V24 though no service packs, the others might work as well I found it it was some problems with some of my cables I had.

Well I think I have it working... should this combine the bandwidth or is this load balancing? I noticed if I do a bandwidth test it like randomly picks a wan to use and I seem to keep losing my connection with them both running... but I have verified that both VLAN's are pulling a ip and are functioning but I'm just not sure if its working right. Any help would be appreciated.
