I am having the same issue. below is my scenario

 

 

Server A IP: 10.82.26.x/24 - Internal VLAN-A

 

NAT'ed External IP: 10.82.126.x/24 - External VLAN-B

 

 

Server B IP: 10.82.86.x/24 - Internal VLAN-C

 

NAT'ed External IP: 10.82.186.x/24 - External VLAN-D

 

 

Default Route on the F5 is 10.83.128.1

 

 

Issue is I am able to ping machines in the remote datacenter from Server A and Server B, but cannot SSH / RDP to any machine. The TCP connections are being reset. Since we have multiple VLAN's per VLAN default gateway as mentioned in the article above is not an option because the source IP of the server will be the SNAT IP instead of the NAT IP.

 

 

Any idea why NAT's won't work in multiple networks.

 

 

Thanks
