I'm sorry, I quite misunderstood your problem (and RW's response). You cannot use ipfw for this purpose, as it only distinguishes source and/or destination IP addresses and/or TCP|UDP port numbers on packets. You need something to distinguish between URLs, that isn't the firewall but something at a higher level, perhaps some sort of proxy? cheers, Ian > *With best Regards,* > > Kulamani Sethi, > Bangalore, India > Mob: 9686190111 > > On Fri, Jul 14, 2017 at 10:31 PM, Ian Smith <smithi@nimnet.asn.au> wrote: > > > On Fri, 14 Jul 2017 16:43:56 +0530, Kulamani Sethi wrote: > > > Hi, > > > I want to set a rule for a particular service URL which running on a > > remote > > > server. > > > I know the IP but don't know the port number where that service is > > running. > > > If i set rule for IP then it will applied for entire services running > > over > > > there. > > > > > > There is a option in IPFW rule we can set either port number or name, > > but > > > it does not accepting using name.
