Works like charm.

Thanks alot.

Without configuring the p255p1 and em1 the network ainºt working.(as i have no connection to server)

It works like this :

auto em1 iface em1 inet manual bond-master bond0 bond-primary em1 auto p255p1 iface p255p1 inet manual bond-master bond0 auto bond0 iface bond0 inet static bond-slaves em1 p255p1 bond-mode 2 bond-miimon 100 address 192.168.137.51 netmask 255.255.255.0 gateway 192.168.137.1``` and this is what i get : ```root@fog1:~# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: p255p1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000 link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff 3: em1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP group default qlen 1000 link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff 4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff inet 192.168.137.51/24 brd 192.168.137.255 scope global bond0 valid_lft forever preferred_lft forever inet6 fe80::ea39:35ff:fe63:fabb/64 scope link tentative dadfailed valid_lft forever preferred_lft forever```

@mitzayapa Great to see that you were able to fix this yourself. Looking at the packet dump helps quite often!

Please start a new thread since your issue will get lost in this thread’s title.

But it sounds like you have two dhcp servers running in your environment.
