I need some help how to allow smtp traffic to a exchangeserver on lanside.
access-list out-to-in permit tcp any host 192.168.0.3 eq smtp
access-group out-to-in in interface outside
static (inside,outside) 192.168.0.3 xxx.xxx.xxx.244 netmask 255.255.255.255 0 0
Do i need to work with more outside ipadresses? Maybe it could be a bad overlap?
