I've double checked my front-end physical firewalls and port TCP/UDP 4172 is open for my security server but i've no matches on it.
access-list outside line 9 extended permit udp any host 10.80.8.1 eq 4172 (hitcnt=0) 0x304ff0bd
access-list outside line 9 extended permit tcp any host 10.80.8.1 eq 4172 (hitcnt=0) 0xfc6140ca
i can see traffic on ports 8443, http and https.
Thanks,
N.
