hi team.
Recently, We've got concern regarding site-to-site vpn between cisco ios rotuer(2600) and checkpoint firewall vpn.
The main issue is slow network connection through vpn. I don't know why it is too slow.
It is too hard to modify checkpoint firewall. we can modify cisco ios router only.
So, could you give some advice to clear this issue?
We think the main issue is MTU, so, we are going to change mtu size in router interface.
Is it ok if we configure only router not in checkpoint?
and could you give us any idea to kick out this issue? any vpn feature could be ok.
