Hi, i have a dedicated server on Ionos with Proxmox.
Server wan interface is enp35s0
Has a public ip 217.xxx.xxx.10/32
I have an additional ip address that ionos delivered me via vlan1010 for using it in virtual machine.
iface lo inet loopback
iface enp35s0 inet static
iface enp36s0 inet manual
iface enx2ecbfb84894d inet manual
auto vmbr0 <-----RouerOS has his ether1 in this bridge with ip 217.xxx.xxx.164/32 and work it can go in internet and receive all ports and protocols
iface vmbr0 inet manual
post-up ip link set vmbr0 promisc on
post-down ip link set vmbr0 promisc on
iface vmbr1 inet manual
iface vlan1010 inet manual
In RouterOS CHR i am able to receive gre connection, i have set a pptp server and from a remote side i am able to connect on it with a pptp client, seems everything work ok except EoIP tunnels... in ip firewall connections i can see outgoing eoip gre connection stuck in "confirmed state". I don't have any in/out firewall rule but cant see any incoming connections.
I have read around about try to set Promiscuous Mode in interfaces and bridges for solve this problem, i have do some test but still not work
Is my first time approaching promiscuous mode on linux, the interfaces seems to be in promiscuous mode right?
