No internet on VLAN

[CyberSenseSteve]

Hi All

I have just built a new router, loaded it up with opnsense and started to build out my network. I have 1 main network (10.0.77.1/24) and two VLANs (10.0.100.1/24 and 10.0.88.1/24).

I have setup the two VLANS using the same methodology (or at least I think so), but the 10.0.88.1 network does not have internet access. Here are some screenshots:





The interfaces are assigned.

Here are my firewall rules which I have for testing. I left these open until I know where the problem is.



DHCP is configured. When I connect to the network I obtain the correct IP address with the correct DNS settings as well. For this network I set the DNS to 9.9.9.9 and 8.8.8.8.

However, I just cant seem to get internet access on this VLAN. The settings on my other VLAN (10.0.100.1/24) appear the exact same but I get access on that VLAN, just not this one. I have checked NAT and the automatic rules do seem to include this particular VLAN.

I am stumped. Any help would be appreciated. Thanks so much.

A good start would be to specifically describe the error mode.

"Internet doesn't work" can be tons of things.


So when you ping, what exactly is the error message?
Further steps:
Check host configuration for route and dns. Is it as expected?
Check firewall live log for incoming blocked packets?
Check interface traffic on WAN: Is NAT really working or do packets leave with their internal IP?

Hi Saarbremer

I reinstalled opnsense and began the configuration afresh with the same firewall rules. After the reinstall, everything seems to be perfect. I still don't know what the original problem was, though, because the firewall was allowing the packets through under the "Live" sessions, but there was no internet.

Thanks again though.
