Hi All,
I use Urbackup since one years for save all data in my company.
Recently i’ve setting the security setting on my debian Backup server.
For this reason i’ve add the rules on iptables, set sudo and create admin account and install portsentry.
Just after that, all backup no longer worked
I’ve check all the rules but i’ve a same issue each time i want to start a backup
Server : Debian 7
Windows server : Win 2008, 2012 and 2016
Urbackup srv version : 2.2.10
Urbackup client version : 2.2.6
Iptables rules for Urbackup :
#UrBackup iptables -t filter -A OUTPUT -p udp --dport 35623 -j ACCEPT iptables -t filter -A INPUT -p tcp --dport 55413 -j ACCEPT iptables -t filter -A INPUT -p tcp --dport 55414 -j ACCEPT iptables -t filter -A INPUT -p tcp --dport 55415 -j ACCEPT

For the moment if i stop firewall on debian server i can backup all the client
Have you an idea where the problem come from ? I’ve forgot to add a port in iptables rules ?
Thank’s for your help
