Cable Forum - View Single Post - VM Business Issue since moving to 5 static IPs

Seb, this has me really stumped…

Unfortunately, if it isn’t an MTU issue, the likelihood of us being able to resolve this ourselves is slim.

Let’s focus on what Verifone are saying, the transaction gets sent out on one port and comes back on another. This is quite an ambiguous statement, making it hard to decipher what they mean.

I’ve been wracking my brain trying to think what it could be, but nothing I come up with makes any sense. It unlikely to be TCP/UDP ports, otherwise nothing would work… Any sort of PC port doesn’t even make the remotest bit of sense either.

If you go back to a dynamic IP address, won’t you have the same PCI compliance issue? If you explain the Hitron is outside your firewall, will this appease them?

Alternatively if you know the IP address the terminal is trying to connect to, I would copy and paste a trace route into an e-mail to Virgin Media support… Explain the issue you’re having, the steps you’ve taken to resolve the issue and how it’s working on your ADSL backup with the same router.
Hopefully they’ll be able to diagnose the cause from their end.
