Cisco SG300 28 and RV345 VLAN Setting

[saids3]

Hell0 All –

I need your help in this configuration please.

I have setup below setting in both Firewall and Cisco Switch SG300 -  

1. Cisco Firewall RV345 set with two VLANS –
   1. VLAN1 (Default) – 192.168.1.1 – Untagged – Port 1 – 255.255.255.0 – DHCP enabled.
   2. VLAN2 10.200.20.1 – Tagged – Port 1 – 255.255.255.0 – DHCP enabled.
2. Cisco (L3) Switch SG300 28 POE+ 
   1. VLAN1 (Default) – 192.168.1.1 – Extended – All The Ports except Port GE5 –
   2. VLAN2 (NEW VLAN Created) – 10.200.20.0 – Untagged – Access Mode – Assigned Port GE5 –

• Usually the routing in Cisco Switch SG300 is happening automatically once I connected any devices –
• My issue is I’m not able to get internet connection from GE5 if I connect a PC or WiFi Access Point? I can Ping 10.200.20.1 - 
• I'm not sure if I need Static Routing in Firewall RV345? and How can be done or what would be the Destination IP and Next Hop and also the Interface? 

I would appreciated the support in this case???

Thanks –

Hello,

from what you are saying it looks like you have the same IP addresses and IP address space on both devices ? One (preferably the SG300) needs to be in layer 2 mode for your setup to work, and the link to the RV345 needs to be a trunk link...

Thank you for the reply 

The link between switch and RV345 in "Trunk Mode" I have changed and still not getting IP or internet connect - 

I dont know about the L3/ or L2 - if going to make any different - because mostly recommended to be in L3

Hello,

make the SG300 a layer 2 device and check if the machines connnected to GigabitEthernet5 are getting IP addresses...

Thank you for the reply - 

I returned the switch to L2, unfortunately didn't work! 

I'm still stuck and unable to have the second VLAN is working - If anyone would illustrate the right way to do this from CISCO? please. 

Here is some information about if the switch should be in L3 or L2.

How did you fix it ? Were you able to keep the switch in L3 and NAT the VLAN internet traffic on the RV345 ?
I am looking to buy SG350 and still searching for an affordable router to make me able to get internet access for all the VLANs I want.
