What does !H in the third line mean? The manpage doesn't mention it.
Host unreachable. 13 51.148.143.104 63.072 ms 58.125 ms 59.895 ms 14 51.148.143.104 3056.713 ms !H 3045.398 ms !H 3036.229 ms !H So host 51.148.143.104 returns "host unreachable" when it forwards connection request to port 8197. Assuming that host 51.148.143.104 is your router, you need to check its port forwarding configuration. It does not look related to openSUSE at all, unless host 51.148.143.104 runs openSUSE.
