Re: Max outbound connections to different servers limited to 65k

[ArcosCom Linux User]

Don't remember fine, but:

For the conntrack table allow more entries, put the value here:

/proc/sys/net/ipv4/ip_conntrack_max

And (I don't remember this) there are another one for the kernel routes
table size.

Perhaps taking a view into kernel documentation installed in your system
or in www.lartc.org you can find those.
