comment Packages drop when using iptables NAT
Hi davidgo, sorry for the word packages, yes its packets actually. Both words mean same thing in my language so sorry for the confusion. I believe its not a hard limit as there are only ~300 servers behind NAT and there is only (Server Count)x2 amount of NAT rules.

comment Centos randomly stops communication with public internet
Yes there are two network cards in each server. Each network card is on different VLAN and it is connected to different converged network cards.

comment Centos randomly stops communication with public internet
Hi Sverre, thank you again for your answers. We checked gateway and DNS unlimited times but we didnt see any problems. There cannot be IP problem because the IP pool is brand new and its all 10.8.X.X. DMESG and SYSLOG says nothing (this is where it becomes annoying) I will add my comments about network cards in next comment

comment Centos randomly stops communication with public internet
@devicenull sorry for not telling it before, I must have forgotten it. There is also another edit I have made. About tcp_keep_alive options. Also there is SRX3400 managing NAT's and it does have lots of resource to manage NAT, so I dont think the problem is on that.

comment Centos randomly stops communication with public internet
@devicenull The weird point is there is no log about this and server does not change IP. However I will try to check if keep_alive option creates such problem.
