I can't apt-get update. Connection timed out.

I blocked some IPs with iptables, iptables-persistent and ipset lately, and I must've blocked a wrong address. I can't apt update at all anymore..
I resetted iptables, reinstalled it, autoremoved ipset.. Nothing works. I could only update kali properly when I booted into recovery mode..

'update' is an alias for apt-get update & apt-get dist-upgrade

I want to somehow reset all traffic rules to default.. Thanks

iptables is not persistent and a reboot resets it. There must be a script somewhere that runs at boot. You'll have to find that script and remove it from the boot. Or you can reinstall.

Just FYI, ipset will not do anything by itself, even if a set is populated; it must be used by an iptables rule.

Its resolved. Today I remembered that I also was toying around with proxies before this problem occured. It turned out that I've set a permanent http proxy and forgot about it. The proxy is now dead and that's why there's no connection.

Deleting the lines I've added for the proxy in /etc/environment and /etc/profile fixed the problem.
