Thread starter janton Start date Nov 6, Joined Sep 17, Messages Hello All, I have to make a A-record on my website to use for a own written pc program. This i named "test" So i point my programe to my website: test.
Than i thought maby it's because there is a firewall or some.. I only have this problem with my new Mac and the firewall is off. If the ports are not blocked software run with windows , the firewall is off, it must be somethig else blocking the software.
Any other suggestion? Based on what you guys said, I believe I may be having some different issues. The sofware runs with my old PC, but does not run with my new Mac. It means that I don't have my ports blocked. Also, my firewall is off, so it is also not the problem. I don't know what could be blocking this softaware to run in my mac. I suspect it is that Comcast router. I had read so many posts on these forums about problems with the Comcast modem-router, that I insisted on a modem without a router as my current wireless router has always worked perfectly.
I exchanged the modem-router model they provided for a modem without a router and it works perfectly with my Apple Extreme router. You might want to search the forums for problems with Comcast router and see if you can see any similarities to your issue.
May 4, PM in response to frazzm In response to frazzm But do you think this problem with comcast router would only happen with Mac, not Windows? Because I only have problems with my Mac. I can't say for sure because I don't use a PC. But I saw enough threads on these and Comcast forums about problems with the Comcast modem-router that I wouldn't even try it. When I got the notice that my old modem was no longer supported, they sent me a new one which included the router.
I didn't even try it, just exchanged it for a model without router. Try searching these forums for Comcast router problems and see if they seem to relate to your issue.
Did you recently upgrade your Comcast equipment and did you have problems with a previous router? If you recently upgraded that equipment and the problem is new, I suspect the Comcast equipment. I've never had a Mac before, so I can't tell if it is something new or not. But right now, if I test my Windows, it works.
If I use my Mac, it doesn't. I was already thinking about buying an AirPort Time Capsule, do you think it will work? In this case, should I downgrade the Wirelles Gateway from comcast and take the one that is just the modem?
Or maybe I should just buy a new modem and forget about comcast. How are you using UseNext? Are you hoping that the Internet can see these ports on the Mac? Or are you just wanting the ports to work on the local network? Does your Windows box already receive these ports from the Internet? If this is the case your router is forwarding these ports to the IP of the Windows box. There can only be one destination for this 'incoming port' on the local network.
If you are not accessing the Mac from the public Internet the router port forwarding is not the issue. I do want to make it clear, that with no exact knowledge of your software or equipment, I only offered a suggestion for a possible solution.
Obviously, it would help if people who know more about networks than I do would offer some advice. I would not want you to change out your equipment without investigating the issue completely. I am no expert and merely offered a possible avenue for investigation.
TCP guarantees delivery of data and also guarantees that packets will be delivered on port in the same order in which they were sent. Because protocol TCP port was flagged as a virus colored red does not mean that a virus is using port , but that a Trojan or Virus has used this port in the past to communicate.
