VE connectivity problems. OUT to IN not working IN to OUT working perfectly

description: Hi, I am experimenting hard problems with connectivity in only one container. All connectivity of this vps is down when atempt to connect from outside (and all static ips assigned to this container). In master node i can ping to ve ip without problems. And inside the problematic container i have all access to outside, appears be ok (i only can access, via vzctl enter $id in master). Also comment, my hardware node is in another subnet. And connect problems are random, sometimes goes online and get offline time ago. But only in one vps, the rest of vps are in the same subnet and working perfect at now. Here a tracert from a ve without problems and the problematic container: Damaged VPS: root@server [/]# tracert terra.es traceroute to terra.es (213.4.130.210), 30 hops max, 40 byte packets 1 x-x-x.XxX.com.com (x.x.99.21) 0.087 ms 0.054 ms 0.056 ms 2 hos-tr4.juniper3.rz4.hetzner.de (213.239.244.193) 0.658 ms 0.703 ms 0.766 ms 3 hos-bb2.juniper4.s04.hetzner.de (213.239.240.139) 0.774 ms 0.786 ms 0.591 ms 4 lambdanet-ffm-gw.hetzner.de (213.239.247.206) 4.013 ms 4.071 ms 3.922 ms 5 ffm-b3-link.telia.net (213.248.68.205) 4.009 ms 4.052 ms 4.071 ms 6 ffm-b2-link.telia.net (80.91.251.226) 3.961 ms 3.981 ms 3.967 ms 7 telefonica-ic-127710-ffm-b2.c.telia.net (213.248.89.90) 29.474 ms 28.370 ms 28.318 ms 8 xe3-0-0-0-grtfraix3.red.telefonica-wholesale.net (84.16.14.162) 3.857 ms 3.913 ms 3.884 ms 9 So-2-3-0-0-grtlont1.red.telefonica-wholesale.net (84.16.13.234) 19.434 ms 19.423 ms 19.510 ms 10 So2-1-0-0-grtmadde2.red.telefonica-wholesale.net (213.140.43.221) 38.165 ms 38.075 ms 38.143 ms 11 So4-1-0-0-grtmadrr1.red.telefonica-wholesale.net (213.140.36.189) 36.520 ms 36.479 ms So3-3-0-0-grtmadde2.red.telefonica-wholesale.net (213.140.37.9) 40.560 ms 12 158.Red-80-58-75.staticIP.rima-tde.net (80.58.75.158) 40.058 ms So-1-3-0-0-grtmadde2.red.telefonica-wholesale.net (213.140.38.249) 43.065 ms 43.077 ms 13 158.Red-80-58-75.staticIP.rima-tde.net (80.58.75.158) 44.266 ms 44.011 ms 43.577…

PARTIALLY SOLVED: VE connectivity problems. OUT to IN not working IN to OUT working perfectly

description: Well the problem was with iptables. Service iptables stopped solves (at this time) all networks problems OUT to IN. However, i need iptables on my container for manage iptables rules (via apf or csf in this case), so i mean that need enable some iptables rules or something to solve this hard routing issues. Any kind of help is higly appreciated. Thanks!

description: Uninstalling csf or disabling iptables service was not the definitive solution. Connectivity problems still appears random. I contact my provider to verify and discard routing issues.
