I am trying to use multiple ip addresses and run the same port. This is for multicraft and dedicated ip addresses.I have the network interfaces setup as:ifcfg-eno1ifcfg-eno1:0 ifcfg-eno1:1ifcfg-eno1:2ifcfg-eno1:3and just changed the ip addresses to 192.xxx.xxx.147,148,149,150.When I ping it does return to the server but when I try to use multicraft it has failed to bind to the port.Here is the interfaces (just ip changed per one)DEVICE=eno1ONBOOT=yesNETBOOT=yesUUID=14081356-1da3-49ca-a25d-3ed9fe2fcd32IPV6INIT=yesBOOTPROTO=noneTYPE=EthernetDNS1=127.0.0.1DEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_FAILURE_FATAL=noIPADDR=192.xxx.xxx.146PREFIX=29GATEWAY=192.xxx.xxx.145IPV6_PEERDNS=yesIPV6_PEERROUTES=yesThe

Multiple ips with same port
linux;networking
The allow multiple instances of multicraft on the same machine, all using the same port, you will need to set a specific address to use for each instance.  If the instance is configured to use 0.0.0.0 it will bind to all interfaces, and any other instances will fail to bind.Example of One instance, one address:## The daemon will listen on the following IP/port.## 0.0.0.0 to listen on all available interfaces (all IPs). Note that## you will have to use the externalIp setting below if you set this## to 0.0.0.0 as the control panel needs to know where to connect.ip = 192.xxx.xxx.147port = 25465Note that you will need to change the 192.xxx.xxx.147 to a real address.
