Hi SoftEther Forum Staff and thanks for your great solution.

- Jumbo Frames Do Not work between PC-A.24 and PC-B.25.

SETUP:
[PC-A.24]192.168.2.24 ------ 192.168.2.1[SoftEtherVPN Server]192.168.1.1 ------ 192.168.1.2[SoftEtherVPN Bridge]192.168.2.2 ------ 192.168.2.25[PC-B.25]

Network 1: 192.168.1.0/24 <- jumbo frames work alright.
Network 2: 192.168.2.0/24 <- no jumbo frames.

DETAILS.
- SoftEther VPN 4.14 Build 9529 running on 2xWindows Server 2012R2.
- Windows 8.1 Pro on PC-A.24 and PC-B.25.
- SoftEther VPN component used: local bridge-only (No NAT/No Firewall/No SecureNAT).

Thanks for any replies and Regards,
Andrea.

Is this still the case?

The link does not seem to answer the question from what I gather (no mention of MTU or packet sizes).
