Hi Noel.
My postrouting chain contains following entries:

Chain POSTROUTING (policy ACCEPT)

target     prot opt source               destination

MASQUERADE  all  --  10.0.0.0/24          anywhere

MASQUERADE  all  --  192.168.2.0/24       anywhere

MASQUERADE  all  -- !cpe-86-xx-xxx-xxx.static.xxx.net  anywhere

MASQUERADE  all  --  anywhere             anywhere            MARK match
0xd001


I've tried to log all packages in different chains (see part of log at
bottom) and I didn't find any traces of virtual IP (10.0.0.2), just iPhones
wan IP and server wan IP. Is that OK ?


I've tried:

iptables -I INPUT -j LOG --log-prefix "Luka-log: "

Part of logs(IPs are replaced with "x", 46.x is iPhone IP and 86.x is
server external IP):

Nov 13 19:21:34 vpn: + C=SI, O=Lupo, CN=clientLupo 10.0.0.2/32 == 46.x.x.x
-- 86.x.x.x == %any/0

...

iptables -I PREROUTING -j LOG --log-prefix "Luka-log(nat-PREROUTING): " -t
nat

Logs:

iptables -I FORWARD -j LOG --log-prefix "Luka-log(nat-FORWARD): "

Logs: vpn logs not found


iptables -I POSTROUTING -j LOG --log-prefix "Luka-POSTROUTING-MASQUERADE:
"  -t nat -s 10.0.0.0/24

Logs: vpn logs not found


Any idea what else should I check ?
