usb speed touch 330 sharing

[bob5]

hi i just had a go using ubuntu geek guide
i do the following :
1)sudo ifconfig eth0 192:168.2.1
2)sudo iptables -t nat -A POSTROUTING -ppp0 -j MASQUERADE
this my modem i get : iptables v1.4.1.1: unknown protocol `-ppp0' specified
Try `iptables -h' or 'iptables --help' for more information.

3)sudo echo 1 > /proc/sys/net/ipv4/ip_forward
i get : bash: /proc/sys/net/ipv4/ip_forward: Permission denied

4) next i have to install dnsmasq ipmasq and restart and reconfigure
works fine .
5)sudo ifconfig eth0 192.168.2.1
6)# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE same as 2
7) sudo echo 1 > /proc/sys/net/ipv4/ip_forward same as 3

gedit /etc/sysctl.conf
Add the line “net.ipv4.ip_forward = 1″ to /etc/sysctl.conf work fine

help please
thank you

Well I have to confess to my ignorance I just learned this - the Network Manager applet has an option for this
Right click > Edit connections > mark your connection > Edit > IPv4 Settings > In the drop down menu change to Shared to other computers
Should not be more complicated, but unfortunately it does not always work

So you are not using NM then?
Have to take a look again - I lost a link to a good solution (maybe I already mentioned that )

[bob5]

yes i could not find the framework form http://www.linux-usb.org/SpeedTouch/ubuntu/index.html
so im using usb adsl modem manger from https://launchpad.net/usb-adsl-modem-manager ,it has the framework build in it for my 330 . also after i followed ubuntu geeks guide , i cant update or use install mint or synaptic !!

joseph

The links in your post of November 7 seems to cover most of the Speedtouch part of this
However I am not going to give advice on IPtables as I don't know much about it and the risk of destroying something is very high, not wise to say something in that situation.
I have struggled with IPtables in a Speedtouch ADSL modem and ever since I dislike Speedtouch
I think you can remove and reinstall iptables

Code: Select all

apt purge iptables

Code: Select all

apt install iptables

This should give you back normal functionality
Here is one simple solution (Just remember that Firestarter is not normally running - it makes changes to iptables and then shuts down)
This may even be the easy solution I found earlier but failed to take note of
Remember not to modify iptables directly - it's way to complicated, it's better to use a "Firewall"
Firewall is realy not the correct thing to say as they all (?) rely on and adjust iptables

[bob5]

will do
i'v already tried Firestarter
but no luck
