Issues with Backup Software and Forwarding (IP) Virtual Server

We are having issues backing up servers that are behind the F5 devices. They are on the "internal" F5 network, and our backup server is "external" to the F5.     We have set up a forwarding (ip)...

e.g. 

[root@ve1023:Active] config  b virtual bar list
virtual bar {
   ip forward
   destination any:any
   mask 0.0.0.0
}
[root@ve1023:Active] config  b snat snat_all list
snat snat_all {
   automap
   snatpool none
   origins default inet
}

200.200.200.101 is translated to 172.28.19.80 (selfip).

[root@ve1023:Active] config  tcpdump -nni 0.0 icmp

10:23:04.383676 IP 172.28.19.80 > 8.8.8.8: ICMP echo request, id 63498, seq 1, length 64

[root@ve1023:Active] config  b virtual bar list
virtual bar {
   ip forward
   destination any:any
   mask 0.0.0.0
   rules myrule
}
[root@ve1023:Active] config  b snat snat_all list
snat snat_all {
   automap
   snatpool none
   origins default inet
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
        snat none
}
}

after applying the irule, 200.200.200.101 is not translated.
