MUDEC_01160: Unable to calculate RTT with destination using TCP protocol

Hi There, when I refresh RTT and try to Game Tunnel for Lord of the Ring Online (LOTRO) (North America) I get the following alert -

MUDEC_01160: Unable to calculate RTT with destination using TCP protocol. If the problem persists, please contact the administrator through the Mudfish forum.

I have checked that the correct adapter installed and on latest version of Mudfish - weirdly, I don’t get this issue with the European LOTRO Item on mudfish. When I connect the VPN to LOTRO North America my ping doesn’t change, and the RTT graph just spikes to max. On European LOTRO it actually shows correct RTT ms.

Whats broken with Mudfish LOTRO NA item?

Please help! Much appreciated.

Could you please confirm if the issue is the same with Full VPN mode enabled?

If it works fine with Full VPN mode, it likely means there’s a problem with the Mudfish game item itself. Because the LOTRO NA item hasn’t been updated in a while, the routing information might be outdated and missing newer IP addresses.

To fix this, I will need to collect some game packets. Could you please send me a packet dump using Packet Capture with Mudfish?

Once I receive it, I’ll analyze the routing data and update the item for you as soon as possible!

Hi there - yes it works in Full VPN.
I have uploaded a Packet dump. The LOTRO servers were merged and also upgraded to 64bit architecture last year, this might be why the issue is occurring.

Appreciate the assistance in getting this working without requiring FULL VPN mode.

I’d left my answer on the packet dump topic you uploaded at Private Support menu. Please check it there. :slight_smile: You can find your topics at My Topics link.

Thank you Weongyo - It’s working wonderfully and reduced ping by almost half!
