ROS 7.11.2 BGP Team CYMRU multihop wont connect

Hi,

I am trying to peer with Team CYMRU Full bogons list using BGP Multihop from my loopback address, using CHR with ROS 7.11.2

I can see connections from TeamCYMRU in firewall attempting to connect to me. There is no session listed in BGP sessions table for this peer. All other peers which are not multihop are working fine. Both ibgp and ebgp. Firewall rules to allow the BGP session are working.

Below is the connection config.

name="Cymru-Fullbogons-1" 
     remote.address=216.31.3.81/32 .as=65332 
     local.address=160.129.227.104 .role=ebgp 
     tcp-md5-key="xxxx" connect=yes listen=yes routing-table=main router-id=160.129.227.104 as=328162 multihop=yes 
     address-families=ip 
     output.affinity=main 
     input.affinity=main .filter=Fullbogons

I have disabled/enabled peer, and rebooted router, to no effect.

I have ready this post but as I am not using BFD anywhere its the same symptom but not relevant to me:

Does anyone have any suggestions?

Many thanks,
