AR2220 IPSEC VPN Issues

Hi All,

We replaced our clients cisco router with a HUAWEI AR2220E, but we are now unable to utililse the IPSEC VPN that was working previously. It looks to not even initiate Phase 1 - the IPSEC VPN is being initiated on a Sophos UTM.

Here is output of the log from the UTM (not debug), but can provide that is it will assist;
