FlexVPN, TCP KeepAlive ACK while access to WebServer on CentOS 6

Hi,
I'm struggling with weird problem.
While client is connected over VPN tunnel SSH session to WebServer (172.16.100.2) is working fine but for some reason web service on TCP/16000 doesn't work (getting TCP KeepAlive ACK).

FW on CentOS was disabled during testing.
TCP/16000 is listening on server:
[root@localhost]# netstat -anp | grep LISTEN | grep ":16000"
tcp 0 0 :::16000 :::* LISTEN 2174/httpd
ACL on VPN GW allowing for connectivity to this host (FlexVPN using only standard ACL so port range is excluded).

 

TCP MSS was set to 1374 also IP TCP KeepAlive Interval and retries were set on VPN GW.
I have no idea where is the issue.
