I have a problem with a customer connecting to our AS5200. I don't think\nit's really my problem at all, but he's making angry noises.\n\nBasically, this is a Sonicwall TZ170SP, which has a modem built-in which\ncan, with PPP, act as a WAN port. Now he's dialing up, gets the right IP,\nDNS and gateway, but he cannot ping the PPP-assigned dynamic adderss, cannot\nping any other address on that subnet (including our DNS servers, mail\nserver, etc) but can ping machines on our other subnet or in the outside\nworld. The routing table is pointing 0.0.0.0/0 to the AS5200, which I'm\nfairly certain is correct.\n\nHe says he can dial the unit up to another provider and it works. I've *nix\nboxes, game consoles, routers, Windows, MAC and heaven knows what else\ndialing in, and I've never seen a problem like this. What's more, I'm\nshowing on our router that when he does try to get out to the outside world\nand it works, our router indicates that the dynamic address is trying to\nsend stuff to some outside 150.* address that he says was an old internal\naddress.\n\nAs I said, I've never seen the problem before. PPP is as straightforward a\nprotocol as I've seen, and with the exception of the odd Win98 box with\nhooped networking, it never fails. Any ideas on this one?
