Can't set up multiplayer

[tecknurd]

I get the same issue, but my game does not crash. I just does not show any servers. I have to reboot my router in order to connect to web sites. I have to do this after playing in multiplayer mode in Factorio version 0.13. This "NAT Punching" feature in Factorio is not effective. I rather go into Windows firewall to fix the NAT issue there. Windows Firewall does have an option called "Edge Traversal." The second thing I rather do is setup port triggering and/or port forwarding but I do not know what ports Factorio uses.

I get similar logs as hyperkiller. Is there a way to disable this NAT Punching feature in 0.13. Until there is a fix or the NAT Punching feature can be disable, I downgraded to version 0.12.35.

My network and system setup is as follows.
TP-Link WDR-3500 (TP-Link Firmware)
ASUS P8H77-I
Intel i3-3225
16 GiB DDR3-1600
On-board graphics
Samsung 850 PRO 256 GiB
Steam version of Factorio 0.13 downgraded to 0.12.35

The following is attachment is the log files for each attempt. I setup both port forwarding and port triggering. Setting those in my router does nothing to fix the issue. I still have the issue of multiplayer dropping connection and not able to get a refresh after that. Also it affects my whole network too. I have to reboot my router to clear the issue. I tried with 0.13.1 and it is the same issue.

THIS IS A CRITICAL ISSUE

I paid for fixing the critical issues first not the minor issues.
