We are in middle of merging another company with ours. All computers, printers and servers in that company are using public IP addressing, internally and externally. We are using private IP addressing internally and only public IP addressing externally. We have implemented a firewall between these networks and have tried to set up a static routes but get issues as asymetric routing.
Can someone advise if using NATing and translating the public IP used by that company into one of the private addressing ranges of our company beforing coming to our network would resolve this issue?
Thank you for your advise in advance.

These are private ip addresses:
|RFC1918 name||IP address range||number of addresses||classful description||largest CIDR block (subnet mask)||host id size||mask bits|
|24-bit block||10.0.0.0 - 10.255.255.255||16,777,216||single class A network||10.0.0.0/8 (255.0.0.0)||24 bits||8 bits|
|20-bit block||172.16.0.0 - 172.31.255.255||1,048,576||16 contiguous class B network||172.16.0.0/12 (255.240.0.0)||20 bits||12 bits|
|16-bit block||192.168.0.0 - 192.168.255.255||65,536||256 contiguous class C network||192.168.0.0/16 (255.255.0.0)||16 bits||16 bits|
Are you using any routing protocol, or are you doing static routes?
You will need an edge router that will connect your Company with their Company, then advertise your routes to them and their routes to you.
