Hello Ronaldo, It’s a configuration issue, you eth1 is either a trunk or not.
If your registration VLAN is 102, you can as you said untag it at the VLAN level and get your communication. If for some reason you want to tag it, you will need to make sure that the eth1 is placed into a trunk and allow the VLAN 102 to be tagged properly and then you can verify if you get it. Use tcpdump: tcpdump -I eth1 -e -n -v | grep vlan You should see vlan 102 traffic. Thanks, PS: don’t forget to restart all PF services once you make those major changes.
