F5 and Citrix ICA proxy configuration

hello

i am attempting to configure ICA proxy for a citrix xenapp 7.15 site using storefront 3.x. the F5's are across a MPLS network so require the proxy function to launch applications from remote private networks.

currently the ica file is not being rewritten & proxied back through the F5.

is there a dummies guide to configuring F5 as i am not very familiar in this product

thanks

dave
