hello friends.

i have the vr600 used as a secondary router/wired extender in my network.

i have a 1gbps connection using technicolor dag2232 as the modem and the vr600 connects to the internet through him

im using some software that uses around 200-500 sockets. after a few hours all the connections are timedout. i have shown a friend of mine the main modem log and he told me that this is the issue:

Sat Sep 12 19:09:07 2020 kern.warn kernel: [ 7803.922633] nf_conntrack: expectation table full

Sat Sep 12 19:09:07 2020 kern.warn kernel: [ 7803.922938] nf_conntrack: expectation table full

Sat Sep 12 19:09:31 2020 kern.warn kernel: [ 7827.790750] nf_conntrack: expectation table full

he told me to increase the size of the internal buffer for connections in the router. Increase the size of the connection table in the router. 

my questions are these:

1. how do i do that in the vr600 settings(couldnt find it)? and will it fix this issue?

2. the pc was connected to the modem directly. if i will connect it to the vr600 and change the settings, will it solve it? or it's all about the main modem configurations?

the problem is the main modem is ISP customized so some features was removed.

I WOULD THANK YOU ALOT FOR ANY HELP

PLEASE HELP ME 

THANKS!
