Hello. I have a configuration like the next diagram:
The FW is Linux Firewall. The IPsec tunnel is working, I can ping PC2 from PC1 and viceversa. I also can ping PC0 from PC1 thanks to a Firewall rule and an static route in Router1 that tells the router that he can access subnet 172.26.1.0 trough 172.26.2.2. I can ping from PC0 to PC2.The problem is that I can't ping PC0 from PC2. I've added a rule in the firewall for the subnet 172.26.3.0 and a staic route in the Router2 to reach the subnet 172.26.1.0 trough the IP 172.26.2.2 but it isn't working. If anyone has some recomendation or experience with this type of implementation I'd appreciate the help. Thanks.
PING PROBE
PC1 to PC2 OK
PC2 to PC1 OK
PC0 to PC1 OK
PC0 to PC2 OK----- It works because the ping arrives to PC2 with the address 172.26.2.2 (Firewall IP)
PC1 to PC0 OK
PC2 to PC0 X----- Here's the problem
Again, thank you for your help.
