Are you sure the switch connected to vr1 is configured with per-VLAN STP (this is probably not the switch default). Have you tried running tcpdump on vr1 and checked that you are seeing STP packets within the VLANs. >gateway_enable=3D"YES" >firewall_enable=3D"YES" >firewall_type=3D"OPEN" gateway_enable=3D"YES" will let the system route packets between bridge10 and bridge20 but shouldn't have any effect on bridging packets between (eg) vr1.10, vr2 & vr3. --=20 Peter Jeremy --HcAYCG3uE/tztfnV Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlBChEIACgkQ/opHv/APuIf8qwCgtEu8+0uuCfU0BbeDOJiJ6YGU ml4An1KET0o4371JU/qoERDxglvUfye8 =6Vtb -----END PGP SIGNATURE----- --HcAYCG3uE/tztfnV--
