Dear All,

I want to reach sub interface ip from internet but i can not ping no matter
what i do.


inet 50.x.x.161/28 brd 50.255.203.175 scope global eth3 valid_lft forever
preferred_lft forever

inet 50.x.x.162/28 brd 50.255.203.175 scope global secondary eth3:1
ce public ip which is set up like this

i can reach the ip address  50.x.x.161 from internet but i can not ping
50.x.x.162. i disabled the firewall but still no luck.

i can not ping from 50.x.x.161 but can not ping from 50.x.x.162. like this

hping3 -1 8.8.8.8 -a 50.255.203.161

HPING 8.8.8.8 (eth3 8.8.8.8): icmp mode set, 28 headers + 0 data bytes
len=46 ip=8.8.8.8 ttl=57 id=17110 icmp_seq=0 rtt=27.6 ms
len=46 ip=8.8.8.8 ttl=57 id=17833 icmp_seq=1 rtt=23.3 ms


 hping3 -1 8.8.8.8 -a 50.255.203.162
HPING 8.8.8.8 (eth3 8.8.8.8): icmp mode set, 28 headers + 0 data bytes
