Internal users to be redirected to external

1) I will create a interval F5 VS 10.1.1.1 and create an irule that will redirect them to customer1.com? yes, i think it would work.

What do you mean hardcode the IP address for the external customer.com site? you mean create an external VS that will serve external customer? i understand Aaron means something like this.

[root@ve10:Active] config  b virtual list
virtual internal_vip {
   snat automap
   pool external_site
   destination 10.1.1.1:80
   ip protocol 6
}
[root@ve10:Active] config  b pool external_site list
pool external_site {
   members 172.28.19.251:80 {}
}
