http://ubuntuforums.org – I have squide with dansguardian on a laptop and need to have incoming port 80 forwarded to 8080 so that even if the user tries to change the proxy setting it will still go to port 8080. was told to add the below to /etc/ufw/before.rules *nat :PREROUTING ACCEPT [0:0] -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080 COMMIT iptables -t nat -A OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8080 but do not know were to put them. below is my whole file # # rules.before # # Rules that should be run before the ufw command line added rules. Custom # rules should be adde (Hardware)

I'd like to forward port 80 to 8080. So I tried to edit /etc/syscongfig/iptables:

-A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

But got:

# service iptables restart iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK

i have this iptables and working.

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 0:20 -j REDIRECT --to-port 8080 #bypass SSH iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 23:442 -j REDIRECT --to-port 8080 #bypass SSL iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 444:2082 -j REDIRECT --to-port 8080 #Cpanel SSL iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 2084:2086 -j RE

I am setting up tomcat server on my Centos 5.5 machine. I've been advised to run tomcat on 8080 as non root user and redirect traffic to it from port 80.

I searched and found the following iptables commands for this:# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT -to-ports 8080 # iptables -I INPUT -p tcp --dport 8080 -j ACCEPTI have a doubt:

There are two IPs associated with one physical network interface eth0 and eth0:0.

The following works fine for the first interface:

iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

Howerver the same doesn't work for the second interface:

iptables -A PREROUTING -t nat -i eth0:0 -p tcp --dport 80 -j REDIRECT --to-port 8080

Also tried:

iptables -A PREROUTING

Hello all, I've set up a virtual machine via VirtualBox (both host/guest are Arch x64) as a small development webserver. The VM is connected via NAT and has ports forwarded to the host for SSH and HTTP.

I'm trying to open up port 8080 on my CentOS 5, Apache 2.2.3 server. When I go to ip:8080/mydirectory - it times out.

I'm trying to open up port 8080 on my CentOS 5, Apache 2.2.3 server. When I go to ip:8080/mydirectory - it times out.

i want to make transparent proxy with linux ( centos) ,

i want all incoming connection on port 1000 - 2000 on eth0 forward to eth1 on port 1000 - 2000 in transparent mode

i searched in the net and i found some command

iptables -t nat -A PREROUTING -p tcp -i eth1 --dport 8001 -j DNAT --to-destination 192.168.1.200:8080 iptables -A FORWARD -p tcp -d 192.168.1.200 --dport 8080 -m state --st

I have a web server running on port 8080. I'd like to visit it via port 80, so I did this:

iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-port 8080

it works if i access the server from other machines using

http://ipoftheserver/

but it doesn't work if I access the server from the same machine using

http://localhost/

why is that?

thanks in advance.
