I was researching how to setup a static IP behind a linksys router and found
a thread on linksys support page that explained to configure TCP/IP as
follows:
IP: 192.168.1.20 (multiple static IP's on other PC's would be .25, .30, etc.
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Preferred DNS: 192.168.1.1
I tried the following configuration and still cannot get internet access?
Any ideas?
I also read a thread about setting up port forwarding which indicated the
following configuration for SMTP:
25~25
IP: 192.168.1.3
Does that seem correct?
Either way, I'm just trying to get the configuration right so I can get
internet access. Then I can see if the SMTP Server works with my mail
scripts.
Any suggestions would be helpful.
Thanks,
