APM on Linux Environment
Hi ,
I am a linux user. my computer has been connected successfully to APM VPN network using chrome browser. Tunnel is up, private address is assigned correctly, I can ping internal resource, open tcp connection and access private web server successfully. The issue is, network status on my browser states that I have been disconnected and no traffic statistic appear. I was struggling and found that it's caused by iptables. When I turned that off I got the correct result. But I wonder what rules shall I add to get correct VPN status . please see my attachment for detail view. I tried to log the rejected packet (13) but to no avail
APM public address 192.168.77.119 (VPN gateway)
internal network 172.16.2.0/24
assigned network (tunnel dhcp) 10.10.10.0/24
my iptables configuration :
iptables -L --line-numbers
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT tcp -- anywhere anywhere tcp dpt:5902
2 ACCEPT tcp -- anywhere anywhere tcp dpt:ldap
3 ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
4 ACCEPT icmp -- anywhere anywhere
8 ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
9 ACCEPT udp -- anywhere anywhere state NEW udp dpt:ipp
10 ACCEPT udp -- anywhere 224.0.0.251 state NEW udp dpt:mdns
11 ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ipp
12 ACCEPT udp -- anywhere anywhere state NEW udp dpt:ipp
13 LOG all -- anywhere anywhere LOG level warning
14 REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
Chain OUTPUT (policy ACCEPT)
