Hello to all!
I encountered a problem while using Wireguard. Here is my traffic dump
tcpdump -vnr wg_02-10-2019_03-17-03.pcap | grep 10.10.10.12 | head -n 10
reading from file wg_02-10-2019_03-17-03.pcap, link-type EN10MB (Ethernet)
10.10.10.225.49267 > 10.10.10.12.https: UDP, length 96
10.10.10.12.https > 10.10.10.225.49267: UDP, length 96

10.10.10.12.https > 10.10.10.225.49267: UDP, length 96
tcpdump -vnr wg_02-10-2019_03-47-03.pcap | grep 10.10.10.10 | head -n 10

10.10.10.10.https > 10.10.10.225.49267: UDP, length 96
In this place (02-10-2019_03-47-03) where the address in the dump changes
on 10.10.10.10 and my session breaks.
Where is the IP address 10.10.10.12/32 in lo interface (CentOS7) and
10.10.10.10/30 is enp0s25 and i am using OSPF and p2p session with another
IP / 30 (ASBR)
netstat -puntal | grep 443
udp 0 0 0.0.0.0:443 0.0.0.0:*
-
udp6 0 0 :::443 :::*
-
10.10.10.225 - client with Windows 7 and settings
[Peer]
PublicKey = key
AllowedIPs = 0.0.0.0/1, 128.0.0.0/1
EndPoint = 10.10.10.12:443
PersistentKeepAlive = 30
What am I doing wrong? Why does the destination address change?
