The problem was: The pyhsical Network Card attached to the server bridge was by default doing TCP checksums in hardware (Intel Gigabit Ethernet Adapter, em in FreeBSD Terms), to take this workload off the kernel. So the packets generated by the server host had no valid TCP checksum on them, entered the bridge without seeing the Intel Card and arrived at my VPN Clients with no valid checksum on them. "ifconfig em0 -txcsum" solved the problem. Now the kernel generates the checksums for all packets, they are valid when they enter the bridge and the communication works fine. I'll report this issue to the FreeBSD People. George ______________________ OpenVPN mailing lists https://lists.sourceforge.net/lists/listinfo/openvpn-users |
