Hi Steve,
The reason why we need to NAT IP addresses because of the conflicting IPs, we are currently replacing a Cisco router using an F5.
Here some snapshots from NAT Router:
ip nat pool SUN1 172.26.0.2 172.26.31.254 netmask 255.255.224.0
ip nat inside source list 11 pool SUN1
access-list 11 permit 10.19.0.0 0.0.31.255
ip nat inside source static 10.157.8.84 172.26.210.84
ip nat outside source static 10.103.33.11 10.171.14.111
Here's the flow
Company A <> Router Company A <> F5 <> Router Compny B <> Company B
Thanks!
