Hi all,
Need some help to setup correctly my c921-4P to use Starlink as internet accès connected on my Wan Port.
I can't acces to Internet, Starling is on Bypass mode.
My conf. is:

no specific error just a "ERR_CONNECTION-CLOSED"

where do you connect your laptop ?

-->> only vlan-5's addresses are selected for NAT to the internet
if you want internet for the other vlan's you need to include these for NAT

so my suggestion was not helpfull,
you also tried multiple browsers: "from Edge, Chrome (maybe no dns resolution or www acces)."
so retrieve network settings and check DNS resolution
- on windows pc "ipconfig /all"
- on linux "ifconfig -a"
- (both) "nslookup maps.google.com"
10-20-2022 05:46 AM
Yes tried on mulitple browsers and i confirm you there is no dns resolution.
Nslookup google.com
Server; dns.google
Address: 8.8.8.8
Dns request Time out

check with your ISP if they allow a third party DNS server! (google)
it may be they only allow their own DNS server(s) instead

Hello,
I have not followed the entire thread, but try and add a DHCP pool to your router for Vlan 50, then set your clients to obtain their addresses through DHCP:
ip dhcp pool VLAN50
Network 192.168.50.0 255.255.255.0
default-router 192.168.50.3
dns-server 8.8.8.8

Hello Georg,
Thx for your help, i'm going to setup a dhcp pool on for Vlan50 and will come back with result.

Hi Georg,
Same problem in DHCP.

Hello,
not good, obviously. Looking at the configuration of the switched ports, what is actually connected to these ports, since you configured them as trunks ? What if you just make them access ports ?
interface GigabitEthernet2
switchport access vlan 5
