i have issue about multiple subnet on RV series

[SIRIPHAN SONMANEE]

now i connect RV with 300 series switch with 20 vlan. How i config RV series for NAT all vlan access to the internet ? because i use multiple subnet i can add only 5 vlan for access to the net it's not enough Please advice Thank you for kindly support.

Siriphan,

What RV router do you have? RV models only support up to 5 vLans/ or 5 local subnets.

With the configuration you have, just put the 300 series switch into Layer 3 mode. Use the RV as a router on a stick configuration.  So basically the SG300 will do all the routing. The only thing; you will need is a dhcp server to give out IP ADDRESS for the multiple subnets.

Hopefully this will give you some more ideas how what you can do.

Thanks,

Siriphan,

SG300 switch doesn’t do NAT or DHCP so you would have to have DHCP server on one subnet to issue IP address to multiple devices across Vlans.

RV042 only support DHCP on Vlan 1

You have to use the RV042 to NAT the traffic from SG300 switch. .

So if you want to set the SG300 in layer 3 mode, while having DHCP Server giving out IP address across your network, while the RV042 NAT’s all your traffic. This can be accomplished

RV042

Local subnet 192.168.5.1

Static routes for other subnets,

192.168.10.0/24 192.168.5.254

192.168.20.0/24 192.168.5.254

10.10.10.0/24 192.168.5.254

10.10.5.0/24 192.168.5.254

----------------------------------------------------

SG300 (layer 3 mode)

Vlan 1 192.168.5.254

Vlan 2 192.168.10.1

Vlan 3 192.168.20.1

Vlan 4 10.10.10.1

Vlan 5 10.10.5.1

(You would need a DHCP server on a subnet, having turned on DHCP relay on SG300 switch)

You would have a default route 0.0.0.0 0.0.0.0 192.168.5.1
