I am using RealSecure 6.5 network sensors with a Workgroup Manager. I am
getting a lot of alerts for "IPunknown Protocol". I know that this event is
being raised because of esp protocol being used on our network.
Can anyone tell me how I can create a filter for realsecure to ignore this
any help appreciated,

don't think so. In particular if you use your cell phone to receive
alerts from your IDS and such. Disabling a sysadmins cell phone can
be part of a well planned attack.

I have heard of a cell phone virus for i-mode phones in Japan. Also,
there are some 'DOS' style vulnerabilities in other phones that make
the phone unusable after receiving a specially formated text message.
Usually, 'rebooting' the phone (remove battery...) will fix it.

However, there have also been 'Cell phone virus hoaxes':
