Ztratovost paketu

[Stanislav Edr]

Preji vsem dobry den,

prosim o pomoc pri tomto problemu.
Mam server se 4 sitovkami, ktere rozdeluji zakazniky do samostatnych 
siti. Posledni dny se najednou objevila ztratovost paketu vsemi smery z 
tohoto serveru.

Kdyz udelam ping kamkoliv paket se ztrati s hlaskou:

64 bytes from 213.180.32.2: icmp_seq=11 ttl=60 time=6.53 ms
ping: sendmsg: Operation not permitted

A v Logu messages tomu odpovídá tento záznam:
