Please explain in words what your problem is? Also not a problem with a link. Moved to general support.

Link 172.26.157.161 keeps trying to PPP in my RB, Looks like an OSPF link that has internet running through it based on first picture, I however only have two authorized PPP connections which @Yashiro is one of.

When i login to Yashiro RB it says my IP is 172.26.157.158 and my IP is 172.26.158.94

If you wish for me to look at this can you please provide logins to:

  • Yahiro RB (presumably this is 172.18.172.14)
  • and 172.26.158.94

PM me the passwords.

Pretty sure the traffic was masqueraded by the incorrect rule on that RB (172.26.157.161). It was masquerading WUG traffic incorrectly. So it looked like he was coming from that IP. To be doubly sure change his password. I’ve made a separate post about that RB and it’s innappropriate firewall rules.

Given that both RBs are including internet I will strongly suggest that you upgrade Yashiro’s RB to latest bugfix version or the current version of RouterOS. His current version is not secure (for example)
