I set up pfSense to connect to a remote network (192.168.122.0/24) that only accepts tap connections.
The connection is being initiated successfully.
pfSense (192.168.1.1/24) itself can connect to remote hosts:
pfsense# traceroute -n 192.168.122.1
traceroute to 192.168.122.1 (192.168.122.1), 64 hops max, 40 byte packets
1 192.168.122.1 116.968 ms 54.357 ms 52.655 ms
Hosts on the pfSenses' LAN network (e.g. 192.168.1.8/24) fail to connect:
lan-machine# traceroute -n 192.168.122.1
traceroute to 192.168.122.1 (192.168.122.1), 30 hops max, 60 byte packets
1 192.168.1.1 0.283 ms 0.303 ms 0.379 ms
UPDATE: Running a ping from LAN to a host fails, but tcpdump on pfSense shows that the packets are correctly forwarded:
lan-machine# ping 192.168.122.1
pfsense# tcpdump -vvi ovpnc4
tcpdump: listening on ovpnc4, link-type EN10MB (Ethernet), capture size 96 bytes
11:54:06.975866 IP (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto ICMP (1), length 84)
192.168.1.8 > 192.168.122.1: ICMP echo request, id 23622, seq 106, length 64
What is necessary in order to have the interface route correctly?
(Note that LAN net needs to stay 192.168.1.0/24)
