VPN session in cisco ASA reflect a different source public ip
I tested and manage to establish vpn on my cisco asa 5520 successfully.
On my syslog i can see "anyconnect parent session started" upon my vpn establishment and "webvpn session terminated" upon terminating my vpn session
where the correct public ip used to establish the vpn is reflected. However after the "webvpn session terminated" line, i can see other lines in my syslog, example "Group=vpngroup, username=test, ip = x.x.x.x, session disconnected, session type:anyconnect parent, duration 0h:00m23s, bytes xmt: 0, bytes rcv:0, reason: user requested" where x.x.x.x is not the ip address used to establish my remote access vpn, neither is it the ip related to my vpn infra. I am very sure that the ip x.x.x.x did not establish any vpn to my cisco asa5520. Hence why is it reflected in my cisco asa logs? Pls advise, TIA!
