recently our isp require us to change the ip subnet we were using without, therefore we needed to reconfigure the pix515E v 6.3 by changing the outside ip address and other static translation with servers and exchange.
but after making this transition we are facing no of issues, one of them is that the static translation seems to be not working as i cannot telnet on smtp to our exchange inside nor exchange receving email from outside.
now if i want to remove the static entry and reconfigure it i get this error
ERROR: duplicate of existing static
secondly if you copy paste the entry it accepts it but it does'nt work at all.
