Greetings,
So, having 4 NICs on my server, I decided to do the following:
- bond (LACP) two copper 1Gbps NICs into one and enslave it onto vmbr0, which also has public IP defined on it.
- enslave one of optical NICs (enp67s0f1) onto vmbr 2, which also has public IP and gateway defined on it.
Problem is, I dont get any internet on VMs, that are using vmbr1 as bridge on guest NIC type virtio. If I move gateway from vmbr2 to vmbr0, then VMs on vmbr3 dont get any internet.
Is there a fix I'm to thick to see? Must I specify gateway in some other way on VMs that are not using vmbr3 without gateway? How to google it?
I tried with iptables:
But it doesnt work..
Maybe, to mention, I'm using masquerade to make internet working on VMs:
It doesnt help if I do the same for other vmbr0 like, I think it even stops working on vmbr2

I tried with iptables:
Code:
iptables -t nat -A POSTROUTING ! -d 192.168.4.0/24 -o vmbr2 -j SNAT --to-source 212.xxx.xxx.25
ip route add 192.168.4.0/24 dev vmbr2But it doesnt work..
Maybe, to mention, I'm using masquerade to make internet working on VMs:
Code:
iptables -t nat -A POSTROUTING -s 192.168.4.0/24 -o vmbr2 -j MASQUERADEIt doesnt help if I do the same for other vmbr0 like, I think it even stops working on vmbr2
