DHCP Client Configuration: How to properly set vivso-suboptions?

@teunbruijnen
I have no experience with the 1100's, and their built in switch-ports.

How is the little mirror-port switch setup in the "Vlan 802.1Q section" ?
You are using the excactly same setup for sniffing ISP and pfSense ?
You have not put any of the ports in a specific vlan ?

Maybe JP can help here, he seems to know about the embedded switch-ports.
@johnpoz

We're trying to replace an ISP router with a pfSense, right now we seem to be stuck with sending the dhcp requests from pfSense, with "Vlan 100 tag" - pfSense is a 1100, and OP has bought a little switch with mirroring capabilities in order to debug the functioning ISP DPCP request vs the non functioning pfSense request.

Right now the issue seems to be that the 1100 pfSense WAN interface packages are not tagged w. Vlan100, according to the Wireshark Trace.

I have never used a pfSense w. builtin switchports, and it could be that i'm missing something there.

I am sniffing the ISP & pfsense in the exact same way right now.

The switch setup wasn't done properly!! I didn't know VLAN's had to be configured on that level too. This is what it looked like before changing the VLAN tag to 100:

The ports seemed to be wrong too, changed to this now:

However... Still no VLAN frame included in the DHCP Discover packet.

@teunbruijnen

By switch i actually meant the New switch you got for "wireshark sniffing".
What model did you get ?

As i say i have no idea about how to setup the switch on the 1100.

Could you show the two captures again SOHO & pfSense with the new setup

@bingo600 I am using an Orange Pi R1 for sniffing!

After more trial and error I finally figured out the problem. In the VLANs for the switch, VLAN group 1 wasn't tagged for 'member 3'. Once I enabled this, the DHCP Discover came tagged with the VLAN. It's still quite strange imo, since I don't understand how 'member 3' corresponds with the interface etc.

Anyways I am happy to finally have figured out how to bypass the SOHO router and start using pfsense. It took me around 4 months in total! Learned a lot about networking. Most of it through the replies you posted in this thread @bingo600 so thanks a lot for that!!
