I configured VPN tunnel between PIX520 and PIX501 but the problem is PC2 cannot ping to PC3 even PC1 able to ping PC3. PIX520 have another several sites which are LAN to LAN and PC2 able to ping to them but cannot to PC3 through PIX501. the difference is LAN to LAN and dynamic for PX501. please review the configuration and give me some idea.
1. Network connectivity
<PC1>-(eth)--------------<Rtr1>-(eth)-<PIX520>-(Internet)-<PIX501>-(eth)-<PC3>
|
<PC2>-(eth)-<Rtr2>-(FR)-+
PC1=10.1.99.100
PC2=172.25.26.100
PC3=10.1.38.11
eth=Ethernet
FR=Frame-relay
Rtr1 and Rtr2 have a routing path for PC1 and PC3.
2. tracert at PC2.(from PC2 to PC3)
C:\>tracert 10.1.38.11
Tracing route to 10.1.38.11 over a maximum of 30 hops
1 <10 ms <10 ms <10 ms Rtr2 [172.25.26.1]
2 46 ms 47 ms 32 ms Rtr1 [10.254.253.133]
3 * * * Request timed out.
4 * * ^C
3. "debug icmp trace" at PIX520 . pinging from PC2 to PC3.
