| TCP issues between USG series and Juniper routers? Anyone else seeing TCP issues between the USG gear and Juniper routers? From the Juniper side, we can ping, traceroute, etc (so ICMP works), but TCP traffic is either broken or not registered by the ZyXEL USG (have checked both 100 and 200 series); SMTP and HTTPS do not work for certain.
Traffic originating from ZyXEL to is fine.
If I have ADP enabled with defaults on the USG routers, this is triggered when devices behind the Juniper send TCP packets to the ZyXEL:
»mysecurity.zyxel.com/mysecurity/···RTID=057
Anyone else seen or heard of this?? |

kudos:3 | You need to be more specific about the issue you're having. From your post it's really hard to understand what is it all about.
Describe your topology, what you're trying to accomplish, what's not working?
Did you do packet captures? |

| I'm trying to receive emails from a server behind the Juniper. TCP packets, including SMTP and HTTPS are not making to the SMTP server inside the ZyWALL intact.
If I have ADP on I get the message from my original post. If I turn ADP off the message go away, but even a manual telnet session from behind the Juniper router to the SMTP server behind the ZyWALL doesn't work. This command:
telnet mail.hostname.com 25
receives no response from the SMTP server behind the ZyWALL, and the ZyWALL log show no inbound traffic on port 25, even though it's set to log all port 25 traffic and it is showing other connections on that port.
The only way I can log this is to stick a hub in front of the ZyWALL, as it isn't registering the packets. |

Do a packet trace on the front and back of the USG to compare with and without the hub in front.
