PIX515A to PIX515B, IPSEC tunnel. I can ping from inside subnet A to inside subnet B. I can ping from PIXA at CLI to inside subnet B. However, I can't ping from PIXB CLI to inside A. This doesn't make sense. As stated, I can ping from anywhere in subnet B to inside subnet A, just not from PIXB CLI.
My configs are quite large so I haven't posted them. I can, but I was hoping for some hints as where to look as this must be a common problem.
