X86 Router Info


Recommended Posts

Hi I am wondering if someone could point me in the in the right direction for setting up a nix home router. My crappy blue box is failing surprise! So I was thinking I could ask if anyone has built, a pc as a router wifi and wired/ using OOS, I have a ubuntu box doing nothing, and have read a bit on how to set up some of it but, not sure where to start in the end I would like to ssh to my box and connect to it via http: so that I have the linux back end, with power, but a clean interface for quick tasks.

Untangle would be a reasonable place to start. Also might look into pfSense, m0n0wall, simple iptables for small needs, Astaro...lots of them out there.

Am also thinking about creating a X86 Router and of all the ones out their, I've only heard personal experience with Astaro Security Gateway. So try that one out.

Actually rather than using a full blown pc for this i was thinking of picking up one of those tiny atom/apu based pc's. something you could throw a couple gigabit nic;s in.

the only thing other than the old dfi board i got is some hot ass P4's. i was messing around with clear os the other day on a sff dell i got but being that it's got a P4 520 it acts more like a space heater.

There were a lot of linksys routers that had both overheating problems and ps issues.

There are a boatload of distributions that will do the job. Do forget to include bsd in that too. There is or was an x86 version of dd-wrt, but I never could get the free version to work right. I think I have openwrt on a machine but it sits in the closet unused for now. It worked great for what I used it for. Worked great n a virutal machine also.

If you know how to use iptables, most any decent linux will do.

IPcop, zeroshell m0n0wall pfsense etc etc.

But turning a deb(based) dist into a fw isn't hard at all.

Here's a extremely simple version:



# delete all existing rules.
iptables -F
iptables -t nat -F
iptables -t mangle -F
iptables -X
# Enable routing.
echo 1 > /proc/sys/net/ipv4/ip_forward
# and some good stuff to have enabled..
#no spoofing
echo "net.ipv4.conf.default.rp.filter=1" >> /etc/sysconf.conf
echo "net.ipv4.conf.all.rp_filter=1" >> /etc/sysconf.conf
#no broadcasts
#echo "net.ipv4.icmp_echo_ignore_broadcasts" = 1 >> /etc/sysconf.conf
echo "net.ipv4.icmp_ignore_bogus_error_responses" = 1 >> /etc/sysconf.conf
echo "net.ipv4.conf.all.secure_redirects = 1" >> /etc/sysconf.conf
#echo "net.ipv4.conf.all.send_redirects = 1" >> /etc/sysconf.conf

echo "net.ipv4.conf.all.accept_source_route = 1" >> /etc/sysconf.conf
#echo "net.ipv6.conf.all.accept_source_route = 1" >> /etc/sysconf.conf

# Always accept loopback traffic
iptables -A INPUT -i lo -j ACCEPT

#yes, you should have fail2ban ;)
#/etc/init.d/./fail2ban restart

#fix tap0 forwarding etc.
#clarify - eth1 internet
#clarify - eth0 lan

# Allow established connections, and those not coming from the outside
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
#iptables -A INPUT -m state --state NEW -i ! eth1 -j ACCEPT
iptables -A INPUT -i eth0 -j ACCEPT
iptables -A INPUT -m state --state NEW -i eth1 -j REJECT

iptables -A FORWARD -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT

# Allow outgoing connections from the LAN side.
iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT

# Masquerade.
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

# Don't forward from the outside to the inside.
iptables -A FORWARD -i eth1 -o eth1 -j REJECT

# portforwarding-rules

#iptables -t nat -A PREROUTING -i eth1 -p tcp --dport [port] -j DNAT --to [ip:port]
