Port blocked

Hello,

I use Sophos UTM9 VM home edition.

Behind UTM9 I have a Synology box. It serves two purposes:

• Plex (Port 32400 with HTTPS)
• Management Web (Port 8443)

I set up the Web Protection for forwarding 443 to 8443 for the Synology box.

• I also set a NAT rule hitting the Internet facing firewall IP, to forward the request for port 32400 to my NAS box
• I also set a Firewall rule to allow from Any towards the NAS box for port 32400.

And yet again, my packages are being blocked! I even moved the rule to the top and here is what shows on the log:

2017:03:09-22:46:02 vpn ulogd[5249]: id="2001" severity="info" sys="SecureNet" sub="packetfilter" name="Packet dropped" action="drop" fwrule="60002" initf="eth0" outitf="eth2" srcmac="60:a3:7d:94:5d:df" dstmac="00:0c:29:54:e7:38" srcip="10.10.3.5" dstip="10.10.2.3" proto="6" length="64" tos="0x00" prec="0x00" ttl="63" srcport="64194" dstport="32400" tcpflags="SYN"

Now I don't know which rule is the 60002 but I don't have such a rule and I don't know wh it is blocking it.

I am open to ideas!

Thanks guys!
