Re: Good experience with Syswan technical support
I have now replaced the ADSL modems with old Cisco 678's, configured in pure bridge mode. There's no question that the other modems were causing problems. They were buggy; they didn't follow their own documentation; and they were not standards compliant. The brand doesn't matter, since nearly all consumer-grade ADSL modems use the same chipset and firmware. The Ciscos, by comparison, seem to be very predictable. Setting them up is considerably more complicated, any software engineer with networking experience should be able to figure it out. 
Now that the previous modems are no longer confusing the issue, I can see that the Syswan router seems to have some significant firmware bugs, too. Its possible that I don't have it configured correctly, but the router's documentation doesn't provide enough information to be certain.
The worst problem seems to be with the router's built-in firewall, which is not configurable at all. If I establish any kind of connection to a remote address, and if that leads to additional connections (e.g., a web browser opens an initial link, and I then open additional links to other subpages at the same site), the router thinks the extra connections are a port scan attack and starts dropping packets.
Hopefully Syswan's tech support can/will resolve this. If not, I'll probably look for a used Cisco router. |
