[PATCH v2] Firewall initscript: Restore Tor IPTable rules by manual firewall restart

[Erik Kapfer <erik.kapfer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1556 bytes --]

If the firewall will be manually restart via '/etc/init.d/firewall restart',
the IPTable rules for the Tor relay will be deleted since 'iptables_init' only
flushes and creates inbound and unbound chains for Tor but does not restore the
ruleset from Tor initscript.

For reference and tests please see -->
