EoIP + DHCP Issue

Tue Dec 04, 2018 12:44 am

Hello all!

Goal: Use the Mik2 eth4 to get a 192.168.78.0/24 IP from the bridge1 DHCP Server in Mik1
Problem: Even though the EoIP interface connection is established, when I connect a PC to eth4 (Mik2) I cant get an IP address from Mik1.
Few notes:
1) The Mik1 pptp client doesn't force any default routes.
2) Both Mik1 & Mik2 have a default route through their respective wan interfaces
3) I didnt setup any manual routes. (could this be the issue?)

Image

Any help would be greatly appreciated.

Thank you! Do I need to apply this both in the Mik1 and Mik2?

Yes, I had a similar problem with gateway IP on a bridge and other IP from same subnet reaching gateway through eoips, disabled fast path on all Bridges and I was able to ping.

Tried that, but still nothing. Same behavior.

1. If you use a static IP, can you ping gateway?
2. Are you using keepalive? If no, enable it.

In order to ping 192.168.78.1 from inside Mik2 I need to add a route in Mik2 and route all traffic to 192.168.78.1 from the pptp interface. But even when I do that, the DHCP is not working.

1. Try SSTP, it has a larger MTU
2. Set keepalive on both eoip tunnels
3. Try to set DHCP server and gateway only on eoip and client on the other end and see if it works, exclude bridges.

I had a problem with bridges with two hEX: when the second hEX (all ethernet bridged) was connected to the first one that has another bridge, WhatsApp images were taking too much to download, same with apps.
I've made a reset on the second hEX and configured it again manually and the problem is solved.
I don't know why but 6.43 has something that make bridges created in older versions to work bad.
Now I have the same configuration I had before 6.43, nothing different, but I don't have problems anymore.

Look for L2tp and BCP instead of EOIP
Your goals:
- No MTU Issue
- pptp is unsave
