Synology uses a linux environment but its not the same as adding one for Linux. I have a 418+ and only has one enet connection but I wanted to have an additional IP for my lab and the other for general access. The one big difference is normally I would create a virtual IP but in Synologys case it did not work as it does in Linux so I went a different route.
Instead of creating a <enet>:0 and <enet>:1 as in Red Hat 8 I just added an IP to ifcfg.eth0 for my normal traffic and a VLAN 20 for my lab. Yes I can route through VLAN if I want to but I am restricting traffic on the lab side. Here is how I did it there may be another way but this worked.
Adding IP via CLI
First things first you will want to SSH into your Diskstation
- ssh <synology_ip>
- cd /etc/sysconfig/network-scripts
This is for a backup and RC parses the directory so don’t want any funkyness going on.
- sudo cp ifcfg-eth0 /var/tmp
- sudo vi ifcfg-eth0
# Make sure it looks something like this, using your subnet of course. DEVICE=eth0 ONBOOT=yes BRIDGE="" BOOTPROTO=static IPADDR=10.0.1.166 NETMASK=255.255.255.0 IPV6INIT=auto_dhcp
I am using a VLAN tag of 20
- sudo cp ifcfg-eth0 ifcfg-eth0.20
- sudo vi ifcfg-eth0.20
# Make sure it looks something like this, using your subnet of course. DEVICE=eth0.20 VLAN_ROW_DEVICE=eth0 VLAN_ID=20 ONBOOT=yes BOOTPROTO=static IPADDR=10.20.20.166 NETMASK=255.255.255.0 IPV6INIT=auto_dhcp
Once your done and everything looks good, double check!!! Then you can restart your network or reboot your choice.
- Restart Network
- sudo /etc/rc.network restart
- Check if it took

- Verify ping both IPs

Thats it, I hope you find it valuable.
