I have 2 interfaces setup ge-0/0/1 is where most of my network servers are. I need when some devices go from ge-0/0/1 to ge-0/0/2 they appear to be coming from a 10.1.1.0 address. I also need when devices on ge-0/0/2 communicate to specific 10.1.1.x addresses that its sent to ge-0/0/1 and to a 192.168.1.x device.
Interface ge-0/0/1 = 192.168.1.0/24 inside_lan
Server A = 192.168.1.100 alias to be set on srx = 10.1.1.220
Server B = 192.168.1.101 alias to be set on srx = 10.1.1.221
Interface ge-0/0/2 = 10.1.1.0/24 inside_lan2
Server C = 10.1.1.200
Server D = 10.1.1.201
So if Server A sent traffic to Server C, I would want a flow like:
192.168.1.100 on ge-0/0/1 > Translate 192.168.1.100 to 10.1.1.220> ge-0/0/2 > 10.1.1.200
Server C would beleive that it was receiving traffic off 10.1.1.220. So the reverse would also need to be in place for when Server C trys to contact server A.
You have to configure proxy-arp for the IP 10.1.1.220/32 and regarding policy, If you need bi-directional traffic flow, you have to create two policy: one from Inside_Lan to Inside_Lan2 and second one from Inside_Lan2 to Inside_Lan.
