If you need to redirect traffic from VPN tunnel to eth0 than you must use iptables ro rewrite destination address

Code:
iptables -A FORWARD -i eth0:1 -o eth0 -j ACCEPT
iptables -A FORWARD -i eth0:0 -o eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

after that you need to enable ipv_4 forwarding

Code:
sysctl -w net.ipv4.ip_forward=1

To stay permanent you need to edit /etc/sysctl.conf file

On the other side you must enable input traffic

Code:
iptables -A INPUT -s <eth0> -j ACCEPT

Allow port range using IPsec?

Hi Guys, Please could you tell me if it is possible to have a single rule/filter to allow a certain port range instead of a separate rule for each port? I'm sure it must be possible but I am unable to find the syntax. Thanks Chris (4 Replies)

RACOONCTL(8)						    BSD System Manager's Manual 					      RACOONCTL(8)

NAME
racoonctl -- racoon administrative control tool SYNOPSIS
racoonctl reload-config racoonctl show-schedule racoonctl [-l [-l]] show-sa [isakmp|esp|ah|ipsec] racoonctl flush-sa [isakmp|esp|ah|ipsec] racoonctl delete-sa saopts racoonctl establish-sa [-u identity] saopts racoonctl vpn-connect [-u -identity] vpn_gateway racoonctl vpn-disconnect vpn_gateway racoonctl show-event [-l] racoonctl logout-user login DESCRIPTION
racoonctl is used to control racoon(8) operation, if ipsec-tools was configured with adminport support. Communication between racoonctl and racoon(8) is done through a UNIX socket. By changing the default mode and ownership of the socket, you can allow non-root users to alter racoon(8) behavior, so do that with caution. The following commands are available: reload-config This should cause racoon(8) to reload its configuration file. show-schedule Unknown command. show-sa [isakmp|esp|ah|ipsec] Dump the SA: All the SAs if no SA class is provided, or either ISAKMP SAs, IPsec ESP SAs, IPsec AH SAs, or all IPsec SAs. Use -l to increase verbosity. flush-sa [isakmp|esp|ah|ipsec] is used to flush all SAs if no SA class is provided, or a class of SAs, either ISAKMP SAs, IPsec ESP SAs, IPsec AH SAs, or all IPsec SAs. establish-sa [-u username] saopts Establish an SA, either an ISAKMP SA, IPsec ESP SA, or IPsec AH SA. The optional -u username can be used when establishing an ISAKMP SA while hybrid auth is in use. racoonctl will prompt you for the password associated with username and these credentials will be used in the Xauth exchange. saopts has the following format: isakmp {inet|inet6} src dst {esp|ah} {inet|inet6} src/prefixlen/port dst/prefixlen/port {icmp|tcp|udp|any} vpn-connect [-u username] vpn_gateway This is a particular case of the previous command. It will establish an ISAKMP SA with vpn_gateway. delete-sa saopts Delete an SA, either an ISAKMP SA, IPsec ESP SA, or IPsec AH SA. vpn-disconnect vpn_gateway This is a particular case of the previous command. It will kill all SAs associated with vpn_gateway. show-event [-l] Dump all events reported by racoon(8), then quit. The -l flag causes racoonctl to not stop once all the events have been read, but rather to loop awaiting and reporting new events. logout-user login Delete all SA established on behalf of the Xauth user login. Command shortcuts are available: rc reload-config ss show-sa sc show-schedule fs flush-sa ds delete-sa es establish-sa vc vpn-connect vd vpn-disconnect se show-event lu logout-user RETURN VALUES
The command should exit with 0 on success, and non-zero on errors. FILES
/var/racoon/racoon.sock or /var/run/racoon.sock racoon(8) control socket. SEE ALSO
ipsec(4), racoon(8) HISTORY
Once was kmpstat in the KAME project. It turned into racoonctl but remained undocumented for a while. Emmanuel Dreyfus <manu@NetBSD.org> wrote this man page. BSD
