Nazdar,
nie je nahodou zablokovana ta IP adresa vo firewalle ? Mne pise 
operation not permitted ked sa pokusim napriklad pingnut pocitac, ku 
ktoremu existuje platna cesta (route) ale mam v OUTPUT chaine firewallu 
zablokovanu danu IP adresu.

Napr:

iptables -A OUTPUT -o eth0 -d 172.16.0.0/12 -j REJECT --reject-with 
icmp-host-unreachable

PING 172.16.1.1 (172.16.1.1) 56(84) bytes of data.
 From XXX.XXX.XXX.XXX icmp_seq=1 Destination Host Unreachable
ping: sendmsg: Operation not permitted
