Description (partial)

Samsung AnyConnect on Android 4.4.x fails to launch certain applications such as Jabber and Citrix Receiver etc.
The underlying reason being the use of DNS SRV records, which fails to be tunneled using Samsung AC client. The DNS SRV records query is used for service discovery for such applications. The DNS SRV record queries goes to the wi-fi / 3g / 4g adapter,  instead of the AC client adapter. The source IP address of the DNS queries of TYPE SRV is from the VPN pool.
AnyConnect ICS+ on Android 4.4.x, 4.3 or below works fine
