Currently have a Sophos UTM and Cisco Catalyst switches in the main office. Computers run on default VLAN and receive DHCP address from Windows Server. Phones run on VLAN 10, and recieve DHCP address from the Phone system server. Adding a RED 50 device in a remote office, also attached to Cisco Catalyst switch. The computers there also run on default VLAN, and DHCP address is from the UTM. RED is connecting and tunnel established, computers can talk to everything in home office and remote office just fine. However, phones will not connect. From a computer, I can ping the phone server, and log into it's GUI interface. If found this article, https://community.sophos.com/kb/en-us/132608 and followed the instructions in it .However, when I make the LAN port mode VLAN, I lose all connectivity, both into and out of the remote office. Computers in the remote office no longer pull a DHCP address and phones still can't talk. In the LAN1 VID(s) field I put 1,10 (no spaces).
One thing I notice, when set up the bridge, it says the converted hardware is the RED device, not eth2 as shown in this example in the doc. I cannot figure out how to change the converted device. I did not add a DHCP entry on the UTM for VLAN 10, since the phone server is the DHCP server for the phones.
Also, does the physical eth2 port on the UTM need to be connected? And if so, to what?
Thanks in advance for any help.
