Internet doesn't work

[Crayboff]

I recently installed Firestarter thinking it'd be a decent firewall, but it sort of messed things up so I uninstalled it completely and deleted it from Session. However, now I cannot get onto the internet anymore via Hardy Heron. I have FIOS for internet and it was working fine before, it is temperamental on my Vista but works fine after some bashing it into the table a few times.

Firestarter isn't a firewall as such it is a front end GUI for IPtables which is the firewall that comes preinstalled with Ubuntu. It could be that you have done something to the settings using Firestarter, which would remain even when you have uninstalled it.

whats the output of

$ifconfig

?

[iponeverything]

Fix up your rules and purge firestarter..

sudo iptables -F
sudo iptables -P INPUT ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -P FORWARD ACCEPT

sudo apt-get purge firestarter

I'm sorry I just realized that I accidentally posted this thread twice so I will post the solution in both. Vista was spazzing when I posted it.

Anyway, thanks for the people who helped me. Here is what I did:

sudo iptables -F
sudo iptables -P INPUT ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -X

sudo apt-get purge firestarter

also here are what I have for the $ifconfig:
Before sudo iptables:

Crap, now it isn't working anymore. All i did was install Foxmarks add on to Firefox and shut down the computer then later I turned it back on and the internet doesn't want to work again

[iponeverything]

Something is restoring the the iptables rules..

sudo apt-get remove --purge firestarter

reset your rules again then try a:

iptables-save

[Crayboff]

unfourtanatly reseting my rules again by doing the code in posts above, didn't work.

[Crayboff]

Also, I have partitioned my harddrive using Wubi. Internet works fine in Vista

[Crayboff]

I ran the code that PMT gave me and I post exactly the output it gave me:

boff@boff-laptop:~$ grep -i iptables /etc/init.d/* /etc/rc.local 
/etc/init.d/ufw:    if iptables -L ufw-user-input -n >/dev/null 2>&1 ; then 
/etc/init.d/ufw:        execs="iptables" 
/etc/init.d/ufw:    execs="iptables" 

boff@boff-laptop:~$ grep -i iptables /etc/init.d/* 
/etc/init.d/ufw:    if iptables -L ufw-user-input -n >/dev/null 2>&1 ; then 
/etc/init.d/ufw:        execs="iptables" 
/etc/init.d/ufw:    execs="iptables" 

boff@boff-laptop:~$ grep -i iptables /etc/rc.local 

boff@boff-laptop:~$

Note that I know the last two inputs were unnecessary, but I did it anyway, to show what I got.



Also i ran ifconfig again, incase anything changed since last time it was working. Keep in mind that I saved the resetted iptables:

boff@boff-laptop:~$ ifconfig
