Debian 9 and lan

mhm, every port has its own ip-subnet, different mac-adress and not directly bridged together so i have currently no idea whats wrong…

can you connect the r2 on these ips over the switch?

Yes only wan ip is directly connected to my internet access, if I use wan port no connexion to internet.

Maybe make tests with another kernel

So you can access r2 but not internet? These traffic has to be routed and also need nat if you have only 1 public ip. Default-gateway on clients need to be r2,on r2 next hop from your isp

I have access to internet if I configure lan3 with ip for internet if I configure wan interface no internet (no led on wan interface)

Another issue with lan0 a laptop obtain an IP from DHCP server on R2, but not possible to access to R2 or ping R2.

Thank you.

Tomorrow I upgrade my kernel to 4.14.62

4.14.62 contains second gmac…so you have to set eth1 to up before configure wan

Yes I see that, but with this update all lan interface are ok.

For use wan

On /etc/network/interfaces

auto eth1

iface eth1 inet manual

pre-up ip link set $IFACE up

post-down ip link set $IFACE down

After configure wan

And same for eth0

?

I have access to all service DNS, SSH. But after add lan3 for internet access, I lost DNS and SSH.

I think maybe issue is when routing is activate
