80% Package loss, is this normal?

Hello, I noticed we have a big package loss and we dont know why.

Is this normal ? Or is sompting worng on ower side ?
The port eth5 from the router to switch is 10GB and from switch to server is 10GB.
Only the ISP ar on eth1 and eth2 with 1GB.

Thank you

Hello @CristianD, as for me, this is not a good idea to use range of networks on one interface.
Preferred to use VLAN in this case.


I`m new on Vyos, i use it for 1y now but never had time to play with it and from the beginning we go on live with it.

I dont know how to make vlans or a good way to setup ower network for a good performance.
I setup the bgp and network the way i read on tutorials :slight_smile:

Should i split the ip ranges x gateways on interface eth5 x on eth4 ? I got another interface 10gb

Will be nice to fiind someone who can make me the setup/network in the right way i pay is not a problem i dont whant free, but i didnt founded nobody yet :(, i allways wondering myself is is ok the way i made it and it bothers me.

You say to setup interface like this ?

set interfaces ethernet eth5 vif 100 description ‘VLAN 100’
set interfaces ethernet eth5 vif 100 address ‘xxx.41.177.1/24’

set interfaces ethernet eth5 vif 101 description ‘VLAN 101’
set interfaces ethernet eth5 vif 101 address ‘xxx.41.176.1/24’

set interfaces ethernet eth5 vif 102 description ‘VLAN 102’
set interfaces ethernet eth5 vif 102 address ‘xxx.214.88.1/24’

set interfaces ethernet eth5 vif 103 description ‘VLAN 103’
set interfaces ethernet eth5 vif 103 address ‘xxx.81.181.1/24’

set interfaces ethernet eth5 vif 104 description ‘VLAN 104’
set interfaces ethernet eth5 vif 104 address ‘xxx.34.24.1/24’

set interfaces ethernet eth5 vif 105 description ‘VLAN 105’
set interfaces ethernet eth5 vif 105 address ‘xxx.34.25.1/24’

Yes, correct. In the first stage, I propose to draw the network topology, it will be helpful for better understanding.

Pay attention, if you separate users’ network to VLANs, you need also configure VLANs and on the switch and set mode TRUNK to VyOS port. This safer for the end-users and provide some L2 isolation.

This is the problem, i dont whant to use vlans cuz i won be able to asign easy ips on the servers or vms and somtimes i fix ips on a vm.

I didnt added all the servers on the picture but this is the way we have ower network, and im planing to add another router and switch in with vrrp fail over in case router 1 dies or the switch for redunancy. I got all of them there ready but im afaind to do it on live :slight_smile: first i have to understand better the first setup

It looks like a bad design.
Try to manage vlans and on your PROXMOX HOSTs

If i change and start using vlans is this will fix my issue with the package loss ?

I think yes, you can try temporary keep only one IP address and others delete from eth5

Thank you.

Founded the problem, we have 2 ip ranges /23 and on the bgp was set as /23 but on the network eth5 was /24 i dont know how i did miss this, so i removed xx.34.24.1/24 xx.34.25.1/24 and added xx.34.24.1/23 and all work grate now :smiley:

Thank you
