Had a very odd issue yesterday, I created two new Bi-Directional nat rules [seperate NAT IP's] to the outside world, one worked fine the other did not... One server could not get to the outside world.. The NAT matched [OK], The Security Rule Matched [OK], Searched the configs [and old ones] for any possible clash with the NAT IP "X.X.X.115", Nothing..... I could see some traffic had started hitting that external address, but stopped. Nothing in session browser. On a hunch I changed the NAT IP "X.X.X.117" And eveything now works.. Can't fathom what possibly could have been wrong as routing must be fine, and the previous address was not blocked by security or used elsewhere... I may swap it back and have a play.
