Problem with icmp mode #461

Open mortag opened 1 year ago

mortag commented 1 year ago

Hello Yancey

I currently run the udp2raw app on an android phone, the "udp" and "faketcp" modes run perfectly, but the "icmp" mode can not run on the phone.

I appreciate you if you help me to find the problem.

Regards,

udp

in client side: iptables -I INPUT -s 192.168.43.235/32 -p icmp -j DROP
