Hi, I've configured freeradius, I've got this type network configuration 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet 10.10.6.10/32 scope global lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens160: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0c:29:2f:f4:26 brd ff:ff:ff:ff:ff:ff altname enp3s0 inet 10.251.4.150/25 brd 10.251.4.255 scope global ens160 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe2f:f426/64 scope link valid_lft forever preferred_lft forever 3: ens192: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0c:29:2f:f4:30 brd ff:ff:ff:ff:ff:ff altname enp11s0 inet 10.10.0.25/29 brd 10.10.0.31 scope global ens192 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe2f:f430/64 scope link valid_lft forever preferred_lft forever all requests and responses work as well but when i wanna send coa to my NaS, freeRadius sends it from different IP, meanwhile my NaS accepts packets only from one IP, my loopback IP - 10.10.6.10
