Hi Tinc Mailing-Group, After all the suffering I have finally sorted out the firewall rules, which has made Tinc work properly. Hurray!!! Looking through the mail archives on the Tinc web-site I spotted the following ipchains ruleset, which I then applied to the 'forward' chain in my rc.firewall. The vpn now works properly.... /sbin/ipchains -A forward -s 192.168.1.0/24 -d 192.168.3.0/24 -b -j ACCEPT Regards, Gillian. - Tinc: Discussion list about the tinc VPN daemon Archive: http://mail.nl.linux.org/lists/ Tinc site: http://ftp.nl.linux.org/pub/linux/tinc/
