MTU

[bluesea2010]

Hi , 

How can I change the MTU value for ipsec site to site vpn  to a higher value  

the interenet service provider mtu value is 1500 

is there any point of increasing the mtu value 

Thanks

                  Usually increasing MTU will not be favorable and or might be counter-productive.

Adding to other comments, you need to understand before you tweak the MTU :
