Hi all,
we have a Customer-WLAN with an pfSense connected to a dedicated SOPHOS UTM (430) LAN-Port.
pfSense is serving DHCP for the Network including Option 234 pointing to the Sophos. So far so good, until now all stuff is working.
Whats odd here is:
When i try to add a NEW AP (AP55 e.g.) it gets a DHCP-Address and starts to send TCP Port 2712 to the UTM (IP 1.2.3.4 and the IP from the DHCP-Option 234).
BUT these packets do not reach the UTM. (Packets say: 0 bit, Retransmission ... )
all other existing APs already in the Network can communicate with the UTM (Port 2712) and work as they are expected to do, so the FW-Rules and so on are OK, as these units wouldnt do so if not.
I even tried opening pfSenses and UTMs FW with an any-any-any rule on the specific LAN-ports -> same result
Any ideas what this could be ?
PS: connecting the new APs to the "normal" user-VLAN on the UTM makes them visible immediately in the Wireless-Protection -> AccessPoints list
Kind regards,
Markus
