Hi all

I have an app A and a service B, service B is running on the dea
server(ip 10.0.0.254), app A need to connect with service B through tcp, it
works normally in my LAN, but when I push A to cf, it cannot connect to B,
then I execute bin/wsh to get into the container and ping the host ip,
it's unreachable, as below:







*root(a)18mkbd9n808:~# ping 10.0.0.254PING 10.0.0.254 (10.0.0.254) 56(84)
bytes of data.From 10.0.0.254 icmp_seq=1 Destination Port UnreachableFrom
10.0.0.254 icmp_seq=2 Destination Port Unreachable^C--- 10.0.0.254 ping
statistics ---2 packets transmitted, 0 received, +2 errors, 100% packet
loss, time 1002ms*

But if I ping another host in the LAN. it can be reached!!!








*root(a)18mkbd9n808:~# ping 10.0.0.253PING 10.0.0.253 (10.0.0.253) 56(84)

It's wired!!! my cf-release is cf-175 and I have only one dea server.Does
anyone met this situation before? thanks!
