Unable to figure out appropriate configuration for Home MicroDataCenter running on GS108Tv3
Hello all,
I am trying to configure VLAN and Routing for GS108Tv3 — 8-Port Gigabit Ethernet Smart Managed Pro Switch with Cloud Management.
I tried to set the model tag in this post to GS108Tv3 but weirdly there doesn't seem to be a category for it so I had to settle for using the existing model tags for reference. I have been trying different configuration settings for almost 1 week and I am not sure what is the appropriate working configuration for my use case. I have attached screenshots of all the configurations I made that were relevant to the VLANS and their routing. Please let me know if I am missing any info so I can attach them in the edits to follow.
I have attached Imgur albums for Switch and Router Configurations.

When I try to add 192.168.1.1 to next default gateway hop, I get this error:

Leaving the routing aside to start with, there are several things wrong here.
The VLAN config is something mixed 802.1q and asymmetric VLAN. If the intention is having multiple dedicated 802.1q VLAN, with an IPv4 subnet, all VLAN must be isolated - having multiple untagged VLAN on a port makes this impossible.
Second, 20.x.x.x is a public network, strictly stick with RFC1918 addresses and subnets (CIDR subneting is ok).
Thank you for your prompt reply schumaku.
I wasn't aware of the RFC1918 pool of private addresses so thank you for that, I will implement that IP address change right away.I'm a beginner when it comes to networking so pardon my lack of experience.
Regarding the VLAN config, what would you advise I should do if I wanted 3 VLANs:VLAN5: cloud development VLAN for 3 devices
VLAN10 private cloud VLAN for 6 devicesVLAN20: public cloud VLAN for same 6 devices as above.
I want VLAN 5 to be able to communicate with VLAN10|20 for DevOps purposes for Continuous integration, testing, development and monitoring. I also want the 6 devices to have 2 VLANs (VLAN10 and VLAN20) so that I can access private cloud services via one IP address and the semi-public cloud services can be accesed for now via the secondary VLAN20 IP address (I intend to purchase IP address blocks from ASIN once I have this cluster up and running so that I can use appropriate global IP address instead of RFC1918 private addresses.
Kindly advise what steps need to be taken to configure the VLAN aspect since you mentioned its not possible to have multiple untagged VLANs on single port. Thank you for your time and consideration, it's greatly appreciated.That will be a long way and hard learning curve.
Some hint:
Your RasPi won't have to many interfaces one might guess. So what you do on the hosts (and similar on the switch port) would be to configure this interface with one network unta¨gged (I would suggest using the VLAN 1 as by default all ports on the switch [you need another VPN capable switch to replace the unmanaged unit] defaulting to VLAN 1 untagged to start with). the other networks need to be configured as tagged on tha interface and the neigbouring switch port.
Another problem you will face with this design: There can be only on default gateway - as you intend to use not less than three networks towards the cloud (Internet, public cloud, private cloud) this will becoe a challenge...
